Hi, I'm Radlup, I'm an 18 year old college student in NYC, and I’ve always had a passion for rogue Graveyard manipulation decks such as Batterymen, Madolche, and now Crystrons! Im super active in DLM and Clan and Team Wars, I really love this deck, i have so much fun playing it :)
Hi, I am MetalOverdrive, 22 yo college student, and a huge fan of the rouge decks that have too much text to read and offer shenanigans and multiple plays, such as Noble Knight and Vampires. Crystrons fall in both of those categories. When I woke up and saw the Cybernetic Rebellion Reveal, I fell for the aesthetics of the Crystron toys. Naturally, we had to find a way to make this work, so here we are! We hope you’ll want to play and enjoy crystrons as well after reading this guide!
Crystrons are the WATER-Attribute, MACHINE-Type archetype that got added to Duel Links in Cybernetic Rebellion Main BOX. The main strength of the deck is Synchro summoning, while being able to search the pieces of puzzle you need from deck fairly easily. What makes this deck different from other Synchro-focused decks is the ability to perform Synchro summons during the opponent’s turn, but it’s limited to machine type Synchros only. This opens the new interactions that were previously limited only to cards such as King's Synchro, but unlike those, you can synchro without needing to be attacked. Unfortunately, we didn’t get the full archetype, but Duel Links already has interesting enough tools to make the deck top tier!
This guide will go over a few categories: cards that belong to archetype, and the ones that don’t, sorted by: main deck monsters/spells and traps/extra deck monsters, combo section, skill section, matchup sections and quarion summoning section.
IMPORTANT: if you use auto setting on toggle-button while you have a crystron tuner that can summon something, the game WILL NOTIFY you that opponents is about the end the turn from the Main Phase. This however can be used as a bait if opponent knows it too, since they can decide to resume their main phase after you perform a Synchro summon.
Main Deck Monsters: non-tuners.
All non-tuners except Crystron Sulfefnir have the same first effect where they destroy a face up card you control to special summon a Crystron tuner from the deck. Also all of them have the graveyard effect as well, and you can use only 1 of their effects per turn!
If you use non-tuner effects (except Sulfefnir’s) on the field, YOU CAN ONLY SYNCHRO INTO MACHINES!
Crystron Sulfefnir (2x)Dragon Ice can, nor can it discard the other copies of Crystron Sulfefnir. Unlike other non-tuners, you can destroy both face-up and face-down cards which can enable more plays(see quarion summoning section). Depending on the build, it can be played 1-3 copies. 2 are recommended for consistency.
Crystron Smiger (2-3x)Crystron Ametrix by itself, and graveyard effect that gives you advantage. If you have Smiger in your graveyard you can banish it to search a Crystron spell or trap from your deck. Currently the only target you can search is Crystron Entry, but it’s importance is being FUEL FOR SULFEFNIR and extending your plays! Side note, you can use the effect to search the turn you send it to the graveyard, if you didn’t use Smiger’s effect to destroy something. We recommend running 2-3.
Crystron Rosenix (1-2x)Crystron Entry. You can also destroy the token with other non-tuners for “free” tuners! Recommended number of copies: 1-2.
Crystron Prasiortle (1x)Crystron Entry. It’s graveyard effect allows you to special summon any Crystron monster from your hand which can enable even more combos. Because of its searchability and meta relevant defense, it should be played at 1 copy.
Main Deck Monsters: Tuners
All tuners can Synchro summon machine-types monsters during the opponent’s main and battle phase. There are only 2 differences between them: their levels and where are the resources they use located. IMPORTANT NOTE! If something happens to your tuner after you activate its effect(for example it gets destroyed by Treacherous Trap Hole) you will summon the other material on the field but Synchro summon will not be performed! Other material summoned this way will have its EFFECTS NEGATED as long as it’s on the field!
Crystron Citree (3x)
Crystron Rion (2-3x)Sealed Tombs! It’s recommended to run 2-3 copies.
Crystron Quan (0-1x)Tunermorph: Normal instead.
Spells & Traps
Unfortunately we didn’t get the best trap: Crystron Impact, but the one we got is pretty useful in its own regard.
Crystron Entry (1-2x)Crystron Sulfefnir. - It can be used from graveyard during either player’s turn. You can use it in multiple ways, depending on situation. You might want to change the level of face-up crystron monster for appropriate Synchro, or use it to send a monster you need to activate in the graveyard(for example Rosenix for free token). We recommend playing at least 1 copy, but 2 max.
Extra Deck Monsters
The beauty of Crystron Synchro monsters is their splashability. You can put them in any Synchro focused deck, but they shine the brightest in Crystron decks.
Crystron Quariongandrax (1x)
Crystron Ametrix (1-2x)
Main Deck Monsters
Scrap RecyclerFoolish Burial on legs for this archetype. All Crystrons are machines so you can mill whatever you need. Usually it’s gonna be Sulfefnir to get your other plays in motion, but depending on what effect would help you, you can mill any other non-tuner for their graveyard effects. Definite staple that has amazing level for this archetype’s playstyle. Run 3 copies.
Genex UndineGenex Controller to be able to use the mill effect. While it has stronger body than Scrap Recycler, if you draw all of your Genex Controllers you can not mill anything from your deck. Other advantage of undine is adding a free controller to your hand, which has synergy with skill Tunermorph: Normal. Since Scrap Recycler is already obtainable from Espa Roba, we would recommend not running any copies of Undine, unless you are playing some sort of deck using Sea Stealth Attack and Citadel Whale, or you are playing a 30 card variant.
Spells & Traps
While this deck can work perfectly fine with monsters only, there are a few cards that can make the deck perform more smoothly.
Treacherous Trap HoleCrystron Entry in grave, if you have a Crystron monster face-up, since Entry banishes itself. You can also destroy your own Synchros or Sulfefnir for floating effects.
World Legacy Clash
Cosmic CycloneBlack Rose Dragon or Vermillion Dragon Mech, but by the time you get them out, it might be too late. To prevent all the nasty Paleozoic Canadia and Drowning Mirror Force you use this spell! It’s quickplay, it banishes, it helps trigger lp based skills, such as Cyber Style. Run 2-3.
Pulse MinesSealed Tombs. It’s not as destructive as Treacherous Trap Hole, but it has its merits. Also helps versus matchups that are vulnerable when switched to defense, such as Six Samurai and Vendreads! However, it is recommended that this card only be used as a side deck card if Sealed Tombs is meta, as there are plenty of better cards to use.
Drowning Mirror Force
Concentrating CurrentBeatdown is not enough to cut it. Most of Crystron boss monsters have respectable stats for both attack and defense, which makes Concentrating Current a very potent card to use, especially since it can be used in damage step. In a way, it's reverse World Legacy Clash that can steal games from unsuspecting opponents. It's worth noting that Crystron Ametrix and Samurai Destroyer are at 4000 attack when boosted by 1 Current for perfect lethal damage.
Another card that helps us deal with huge threats in damage step, Mirror Wall provides both protection and utility, while also being one of rare cards to be able to deal with Invoked Cocytus attacking from defense. It offers a bit of extra synergy in Crystron, as you can destroy it with your non-tuners in a pinch to get a tuner from your deck. This basically means that you are paying 2000 life points to special summon monster from your deck, so it should be used wisely. Ancient Gears falling in representation makes this card much better in current meta than it was ever before.
Extra Deck Monsters
Powered InzektronCrystron Citree by Crystron Rosenix ’s effect, or when you want to recycle Crystron Smiger form the banish pile (after using it for either Crystron Ametrix summon or Crystron Entry search). Has decent body and prevents ALL TYPES of damage. Run 1.
Samurai DestroyerFlip Flop Frog, so there is no need to have to wrry about that. He is also powerful against monsters with passive effects that allow them to gain attack or not be destroyed by battle. He will make an Elemental HERO Brave Neos become 2500 atk and will be able to destroy Yubel - Terror Incarnate by battle. He can also safely attck over any DARK Machine type monsters without having to worry about Desperado Barrel Dragon being summoned. Be careful not to attack into a Darklord Desire who used their effect to reduce their own attack, as it will have that effect negated and go back to being 3000 attack. His second effect that allows him to revive himself or any other mchine means he is pretty much unable to be destroyed by card effect, and his effect will apply even when banished by Spellbook of Fate or shuffled into the extra deck by Flip Flop Frog or Drowning Mirror Force, but he will not be able to revive himself as he only revives machines in your GY. However, he can still revive a Sulfefnir for more floating or a Citree/Rion so you can do more synchro plays. He is a staple in the Extra deck and should be ran at 1-2 depending on how many battle traps/flip monsters you are running into.
Karakuri Shogun mdl 00 "Burei"Karakuri Strategist mdl 248 "Nishipachi", which on summon can change the battle position of any monster on the field. This effect is very powerful and can end your opponent's turn, and it is a free level 3 tuner as well, which can enable more plays on your turn. Burei is also a powerhouse as on your turn he can change the battle position of any monster, including your own, enabling many otks. However, in this meta, many decks can spam out enough monsters to overwhelm burei, and there are other synchro monsters worth using over him. Important note, if you chain your Citree or Rion effects to anything Burei will miss the timing and will not summon anything from the deck!
Vermillion Dragon Mech
Extra Deck Monsters
Black Rose DragonCrystron Ametrix or Sulfefnir on field, you get their floating effects. Many synchro decks cannot afford to use this card because it is hard to make plays afterwards, but in crystrons we have many graveyard effects to help recover, and all we need is one measly tuner on board to become a threat.
White Aura DolphinSealed Tombs or being run over with monsters that have effect like Armades, Keeper of Boundaries.
Gungnir, Dragon of the Ice BarrierVermillion Dragon Mech and Black Rose Dragon because the destruction effect is simply too costly. If you don’t win off of its first effect or 2, you can get outpaced very easily. Only run this if you don’t have better Synchro monsters. As a side note, you can’t use Scrap Recycler when summoning it, because Recycler is not a WATER monster.
Beatdown This skill is self explanatory, crystrons like to swarm the board with high level synchros, and beatdown with 2 synchros on field gets you over 3000 attack. This skill is 100% the best way to run this deck in the current meta, as many of our boss monsters need the boost in order to compete with others such as Darklords and Neos.
Level Augmentation This skill requires additional dose of thinking to be utilized well. The idea is, you will be using your higher level monsters already, so they won’t be in your hand (for example Crystron Sulfefnir and Crystron Rosenix). Instead, you will have lower level monsters in your hand that will help you increase the level of the target on the field. This also works really well with Rosenix token and makes it much easier to access anything that will win you the game. And the best part is, since it’s “Skill activation”, your opponent can’t respond to it. For example if you have a Crystron Smiger and Crystron Citree on the field, and activate Level Augmentation with Citree from your hand, you get to nuke the board without interruption!
Level Duplication Similar to the level augmentation, this skill can be used to “downgrade” the levels as well! In our testing we found Aug to have bigger impact overall, but if you want you can run either of these 2. Just a side note, rosenix token is less useful with dupe than it is with aug, especially in situations where you have limited resources.
Tunermorph: Normal This skill is pretty unique, and it has very interesting usage in this deck. In short, it makes your Rosenix token into a level 1 tuner. And as other skills, opponent can’t respond to it which can lead to unexpected Black Rose Dragon or Crystron Quariongandrax from seemingly low-threat boards. It has good synergy with Genex Undine because you will often have a tuner in hand, ready to be used! Shoutout to TCG Cray for making good use of the skill in tournaments!
Free Card Skills You can use any of the “Start with x card active on the field” such as Land of the Ojamas or Master of Rites II so you get card to destroy with your non-tuners, as they can use the cards you have active from skills, as long as they are face-up. This can give you free advantage but it’s risky since your cards can be used against you(they either get banished by Cosmic Cyclone , or give a target for Six Style - Dual Wield and Double Cyclone that otherwise could be played around.) We recommend running Land of the Ojamas and Master of Rites II because they don’t help your opponent in any way, although Master of rites II does take up your spell/trap slots. Other good skill you might want to consider is Light Barrier because it won’t appear until your turn. However the downside is you have to activate it yourself so it can be negated by Legendary Six Samurai - Shi en or Silent Magician. It’s worth mentioning, Bastion has Field Spell skill such as Silent as WATER that have LP requirements. If you use Cosmic Cyclones you can consider running it, as it also boosts all your Crystron monsters!
Cyber Style One of the cheesier skills, but it has a surprising amount of synergy with the deck, if you run Cosmic Cyclones. For each 1000 LP you are missing, you can get place a Proto-Cyber Dragon on the field. You can’t tribute the Protos, nor can you synchro summon using them from the field. However, if you use any of the non-tuners to destroy it and summon Crystron Citree, Citree can use the Proto from the grave for the Synchro summon! Also worth noting, using this skill with Crystron Quariongandrax gives you lethal damage!
This is the deck we feel is best suited for this meta as Enemy Controller and World Legacy Clash
30 Cards 3rd/4th Place MW #85 - Cray:
Cray’s 30 card deck is innovative and has a lot of power plays it can make, and a large surprise factor in the combo that is rosenix token paired with Creature Seizure, making it a very explosive deck.
22 Cards Anytime #16 - radlup:
This is my Radlup deck, and I really like it as it can make multiple plays, most of the combos are explained in the rest of the guide. There are many spaces for techs here, as well as deck size, we can afford 22 cards considering the consistency this deck has with essentially 9 starter card.
And this is my MetalOverdrive deck, after doing the math with radlup, I realised we can do even 23 without problems, because the deck thins itself super fast and first entry searches the second one! This deck won me the first place in heyheycraig’s pro series, so it definitely has merit to it. Also running level augmentation as primary skill, which came in clutch almost every game. Also, Konami give us more extra Deck slots pls.
20 Cards "F2P"
This is an example of f2p list, that requires you to go through the box only once! It’s not optimal but you should be able to have decent practice out of it. Of course, you can add any strong techs or synchros you have to make it better. If you have these already, give it a try!
This deck can work with any number of Sulfefnir copies that’s greater than 0. For the sake of consistency, we’ll go over a number of Sulfefnirs and Scrap Recyclers and how often do you start with at least one copy of those! Running 1 Sulfefnir and 3 Scraps in 20 cards gives you 62.44% chance to open one of those 4 cards on your first turn. However, running 2 Sulfefnir and 3 Scraps in 22 cards gives you 67.46% chance to see one of those in your first 4 cards! This means we can save the consistency even by going over the 20 cards, if we add another copy of Sulfefnir, which in turn lets us use more tech options, since the deck thins itself pretty quickly already. You can play up to 24 cards with 2 Sulffnir/3 Scrap and still have the higher consistency than the 20 card deck with 1 Sulfefnir/3 Scrap. Going over 24 requires you to add more Sulfefnirs or copies of Genex Undine to compensate!
Basic Combos Without Recycler
- Combo #1
- Combo #2
- Combo #3
Basic Combos With Recycler
Typically, you will use scrap recycler to mill a Sulfefnir to the graveyard, so you can use its effect and start to get your combos running. In the case that you already have a Sulfefnir in hand, you can send any of your non-tuners to the graveyard so you can use their effects, Smiger will provide fodder for Sulfefnir, Rosenix will give you a free target to destroy, and Praisotle will be able to special summon additional monsters from your hand. In case you have Scrap Recycler and Crystron Sulfefnir in hand an no other Crystron cards, you can mill Crystron Smiger with Scrap, so you can banish it right away and search Crystron Entry, so you can make further plays with Sulfefnir!
- Example Hand #1
With this hand you want to normal summon the Scrap Recycler -> send Crystron Sulfefnir from the deck to the graveyard -> special summon Sulfefnir by discarding Crystron Smiger -> destroy Sulfefnir with its own effect -> special summon Crystron Prasiortle from the deck -> destroy Scrap Recycler with Prasiortle’s effect to summon Crystron Citree or Crystron Rion (depending if your want to play around Sealed Tombs or not, more on that in later section) -> banish Smiger from the graveyard to search Crystron Entry.
You summon Prasiortle and search for the Entry so you wouldn’t draw them! After that play, you have Crystron Citree and Crystron Prasirotle on the field, Scrap Recycler and Crystron Sulfefnir in your graveyard, and Crystron Smiger banished, while also having 3 cards in the hand.
From this point, you can use Citree + Scrap Recycler on opponent’s turn to make Crystron Ametrix or Citree + Sulfefnir to make Burei, but that wouldn’t be optimal because we have Nishipachi in hand. Since we also searched Entry, we can use Sulfefnir next turn no matter what we draw(if we don’t banish it with Citree, that is)! This game state also setups Quariongandrax for the next turn! If we make Ametrix and it survives for the next turn we can do this play: Special summon Sulfefnir by discarding entry -> destroy Ametrix on summon -> use Prasiortle to destroy Sulfefnir and special summon Citree from deck-> use Sulfefnir’s effect to special summon Crystron Rosenix from the deck -> use Rosenix’ effect to destroy Prasiortle and special summon Crystron Rion from the deck.
This is the game state we have after that play! We can make Quariongandrax without even using our normal summon! Side note, if anything had happened to the Ametrix, you could have normal summoned Nishipachi or Scrap and destroyed them instead for the same result! Also we went from 19 cards at the start of turn one to 11 after all the plays on turn 3. The strength of this deck really shows when you can mill like crazy, even with seemingly “ok” hand. This also shows importance of running 3 Scrap Recyclers.
- Example Hand #2
This hand enables you to play both aggressive and defensive, depending on the board state. If you want to make defensive plays, you can mimic the play from above but with minor changes. Discard Praisotle instead of Smiger to special summon Sulfefnir -> special summon Smiger from the deck -> destroy Scrap with Smiger’s effect to special summon Citree. In this example we’ll focus more on the offensive play:
Normal summon Scrap Recycler -> mill Crystron Sulfefnir from the deck(if you play only 1 Sulfefnir, you mill Smiger for Entry) -> discard Crystron Prasiortle from the hand to special summon it -> Sulfefnir destroys itself and summons Crystron Rion if you want to go into White Aura Dolphin to beat over a strong monster or into Crystron Smiger if you want to go for Ametrix as a safer play, because it will float on destruction. We’ll continue with the Dolphin route: Synchro summon Dolphin by using Rion and Scrap as materials -> banish discarded Praisortle to special summon Sulfefnir from your hand. So far, this brings us the following game state:
If you use Beatdown, this board goes to 5600 damage! And thanks to Dolphin’s effect, this is lethal over any attack position monster with 3200 or less attack! It’s also worth mentioning that this board is pretty tough to go through, because Dolphin revives itself and Sulfefnir floats into any Crystron card, when destroyed (if they destroy it during this turn, it won’t float into anything since we already used that effect once previously!).
On of the biggest strengths of the deck is the sheer amount of floating Ametrix and Sulfefnir provide. If Ametrix gets destroyed, you special summon a non-synchro Crystron from your graveyard. We’ll go over a few situations and how to use Ametrix to its maximum potential!
IMPORTANT NOTE: Neither of Ametrix’ effects is once per turn, but all of the tuners are HARD ONCE PER TURN!
Situation 1 - Defensive Ametrix
If you use Scrap Recycler to mill Sulfefnir, and do the combo from “Example Hand #1”, you will have Citree and and Praisortle on the field. From that game state, you can summon Ametrix on opponent’s turn. If Ametrix gets destroyed, you can now float into Sulfefnir from your graveyard. From there on, we have 2 possibilities, Sulfefnir not getting destroyed and Sulfefnir getting destroyed.
Case 1: Sulfefnir Doesn’t get Destroyed.
If Sulfefnir stays alive, you can:
- Destroy it with other Crystron non-tuners to set up Quariongandrax, Burei, or Ametrix
- Synchro with it
- Use it as a beater while you set up another tuner for Synchro plays(for example Smiger destroy itself for Rion)
Case 2: Sulfefnir gets Destroyed.
If Sulfefnir gets destroyed, you get to choose a Crystron monster from the deck to special summon. Depending on your situation, you can consider these options:
- If you are in under a threat of more destruction, you can special summon Crystron Rion to potentially go into Powered Inzektron and guarantee the survival this turn
- If you want to go to the game state of “Case 1”, you can summon another Sulfefnir from the deck.
- If you are going to summon a machine Synchro, go into a Crystron non-tuner
- If you are going to summon a non-machine Syncro, go into a Crystron tuner
Situation 2 - Offensive Ametrix
If you want to play aggressive with the the relative safety, you can mill the Sulfefnir with Scrap -> special summon it to the field and have it destroy itself -> special summon Crystron non-tuner depending on what you want to set up for the next turn:
- Special summon Crystron Prasiortle, if you want to gain a special summon from hand during the next turn
- Special summon Crystron Smiger, if you want to get another use of Sulfefnir by searching for Crystron Entry
- Special summon Crystron Rosenix, if you want to get a token next turn OR if you think you might need to go into Powered Inzektron during your opponent’s turn
After you decide which non-tuner would you help you the most(usually the Smiger) and special summon it -> use non-tuner’s effect to destroy itself and summon Citree from the deck -> Synchro summon Ametrix by using Scrap and Citree. At this point you can go aggressive with the Ametrix, and if anything happens to it, you get to choose what to summon from the graveyard:
- Citree -> which allows you to go into another Ametrix, or Burei
- Sulfefnir -> see previous section
- Smiger -> only if you want it to destroy something on your turn and you know it will survive this turn!
It’s important to note, there is no floating versus Ancient Gears and effects similar to theirs!
Situation 3 - Nuke Ametrix
Wonderful thing about Ametrix is floating even on effect destruction that comes from your cards! If you manage to get out a Black Rose Dragon - not always an easy task, but when you clear the field and float into something, it can swing the game in your favor!
Skilless turn 3 Black Rose Dragon + Ametrix combo requires opening Scrap recycler + 2 Crystron cards in your first 5 cards most of the time.
With this hand, we want to end up having Citree and Rosenix on the field with Scrap and Sulfefnir in the graveyard. That way, if Rosenix survive, we can make either Quariongandrax or Ametrix + BRD play next turn! Try thinking a bit how would you do it with this hand!
Normal summon Scrap -> mill Sulfefnir from the deck -> discard Entry if you play 1, or discard Smiger if you play 2 Entries -> Sulfefnir destroys itself -> special summon Rosenix from the deck -> Roesnix’ effect destroys Scrap to special summon Citree -> set Clash -> (optional)search Entry with Smiger from graveyard. (Side note: it’s usually better to discard Entry as soon as possible to make its level manipulation and Foolish Burial effect live, but this combo is explained as if you had any 2 Crystron cards) Next turn, you summon Ametrix with Citree and Scrap, which should help keep rosenix alive, even more so with the clash and that will bring us to this state:
From this point, based on what you destroy with your Sulfefnir you have multiple plays but we’ll go over 2 most devastating ones:
- Sulfefnir discrads Entry to destroy itself to special summon Rion -> Ametrix + BRD
- Sulfefnir discards Entry to destroy Ametrix -> Rosenix destroys Sulfefnir to get out materials to summon Quariongandrax From this position you can get any monster from your extra deck in one way or another, so have fun experimenting, and that was all possible with 1 Scrap and 2 Crystron cards.
In conclusion, mastering the use of Ametrix will go a long way in making you a better Crystron player!
Quarion can straight out win games, a level 9 synchro that needs two tuners for its synchro summon. While there are too many ways to summon him that we can list, here are some basic plays, but always keep the math in the back of your head as this deck can summon him out of nowhere.
Crystron Sulfefnir or Crystron Ametrix + Crystron Rosenix or Crystron Smiger. If you have a sulfefnir or ametrix on board, you can summon a Rosenix or a Smiger and use their effect to destroy the sulfefnir/ametrix, and summon the tuners you need to make quarion. As a side note, Sulfefnir has to destroy something when special summoned by its own effect. If you want to keep it on the field, you can set any spell or trap card to be destroyed, or special summon Rosenix Token beforehand. That way Sulfefnir on the field can be destroyed by other non-tuner Crystrons for double search!
Karakuri Shogun mdl 00 "Burei" + level 2 / 3 Karakuri tuner + Crystron Rosenix / Crystron Smiger On Synchro summon you get to summon a “Karakuri” monster from your deck, then on your turn you can summon either of the non-tuners and destroy Burei for the level you are missing to get 9.
“Free Sulfefnir” Combos:
All of the “Free Sulfefnir” combos require you to have Ametrix on the field, Sulfefnir in the graveyard and any Crystron monster in hand. We call them “Free Sulfefnir” because we usually bring the card we discarded back to the field, thanks to Ametrix effect.
- “Free Sulfefnir” Combo 1 - non-Tuners:
If you have Ametrix on the field, Sulfefnir in the graveyard and Crystron Smiger or Crystron Rosenix in the hand you can: special summon Sulfefnir by discarding the non-tuner -> destroy the Ametrix with Sulfefnir’s effect and special summon the discarded non-tuner -> use non-tuner’s effect to destroy Sulfefnir and get appropriate tuners, up to level 9.
- “Free Sulfefnir” Combo 2 - Prasiortle
If you have Ametrix on the field, Sulfefnir in the graveyard and Crystron Prasiortle in the hand you can: special summon Sulfefnir by discarding the Prasiortle -> destroy the Ametrix to special summon the Prasiortle -> Prasiortle destroys the Sulfefnir to special summon Crystron Rion from the deck -> Sulfefnir special summons Smiger or Rosenix -> Smiger or Rosenix destroy Prasiortle for the tuner of appropriate level.
- “Free Sulfefnir” Combo 3 - Tuners:
Same deal as before, Ametrix on the field, Sulfefnir in the graveyard, but this time we have any of the Crystron tuners in the hand, so we have to alter the play: discard the tuner to special summon Sulfefnir -> Sulfefnir destroys itself to special summon Smiger or Rosenix -> the special summoned non-tuner destroys Ametrix to special summon a tuner-> Ametrix revives the discarded tuner.
As it can be seen, it’s really easy to make Quariongandrax with minimal setup.
It’s important to note, whenever you plan on summoning MACHINE Synchros, and you want to summon tuner from deck with Sulfefnir’s effect, you can instead summon a non-tuner that you won’t use that turn! After that, have non-tuner destroy itself to summon the tuner you originally wanted! This causes you to thin the deck even more, and sets you up for future turns. For example, in “free Sulfefnir” combo 1, you can destroy Sulfefnir with Rosenix, and summon a tuner + Smiger from deck, and then have Smiger destroys itself to get a tuner you are missing!
Using Level Augmentation can catch people off guard by making somewhat unthreatening board suddenly produce strong Synchro plays! Also as mentioned before, your opponent can’t respond to skill activation! It is also worth noting that level change stays as long as the monster stays on the field! That can be quite relevant for this archetype, as you can setup level of your tuners for your opponent’s turn! Usually you want to use resources in hand to “level up” the materials on the field for appropriate level, but common examples are:
Making Black Rose Dragon:
If you have level 3 non-tuner and Citree, using any level 2 tuner in your hand makes level 7.
Normal summon Scrap -> mill Sulfefnir from the deck -> discard Rion to summon Sulfefnir from grave -> Sulfefnir destroys itself to summon Citree from the deck. This is the last opportunity for opponent to do anything. Once you activate Level Augmentation, by revealing the other Citree, they already can’t do anything and you get to nuke the field! It’s preferable to nuke the field when you have Ametrix or Sulfefnir on the field so you can float into something, but your opponent won’t always allow that to happen.
If we take a look at “Basic Combos with Scrap” section, we get a look at this state:
If we make Ametrix on opponent’s turn and your Prasiortle survives, you can use the Sulfefnir from the graveyard to get a Citree from your deck. Now, on the field you have level 2 Crystron Citree, level 5 Crystron Ametrix and level 2 Crystron Prasiortle. You can use Level Augmentation to make one of your level 2 monsters level 5, thus allowing you to make Black Rose Dragon and destroy everything, including your Ametrix! Which can then go float into Sulfefnir and in this case you can even use Magnet Reverse on your Ametrix for total of 4600 damage!
Level Augmentation can also turn your Prasiortle into a level 4 non-tuner, so it can be used instead of Rosenix in plays involving making a Quariongandrax!
The more you use the skill, the more opportunities will you see for Synchro plays. Luckily, all of the Synchros used have no hard restrictions, so you can use Augmentation for anything you might be short off, in terms of levels.
- Combos Rosenix Token
Rosenix token is a powerful thing when combined with Augmentation. It can replace virtually any non-tuner in deck, because of its level. There are also two “1 card combos” that can allow you to swing the game in your favor off of only 1 tuner and Rosenix in graveyard! However, these combos require you to make a play after you use the skill, so they can be disrupted! The thing they have in common they is that they require you to special summon token, and use Level Augmentation on it.
1 Card Combo - Citree: Using Level Augmentation on token makes it level 3, which means that your one Citree in hand becomes level 5 Synchro! That’s most often gonna be Crystron Ametrix, which on its own provides with more floating options later on!
1 Card Combo - Rion: Using Level Augmentation on token makes it level 4, which allows you to make level 7 Synchro, which can be Black Rose Dragon or Burei, both of which can change the flow of the game!
Of course, this is not optimal use of the skill. Those combos become much more potent when you have more cards in hand so your Synchro summon becomes unstoppable!
In a way similar to Level Augmentation when used, because you need Rosenix token and a tuner in hand to utilize it properly. This skill also allows you to turn unexpected boards into a massive threats! It also gives you access to “level 1 tuner” on demand, which can be quite strong, since it can’t be responded to. This skill is more versatile in lists that use Genex Undine because you will more often than not have Genex Controller in hand.
There is a lot of possibilities for this deck, but i’ll list only the one that make a very strong impact:
Powered Inzektron + 1 = Black Rose Dragon Usually, when you go into the Inzektron, you can’t do much with it because of its level, but with skill Tunermorph, you can turn it into a Black Rose Dragon with Rosenix token that has now become a level 1 tuner!
Powered Inzektron + 1 + Crystron Citree = Crystron Quariongandrax Same as above, we are using level 6 as advantage here! Inzektron + Citree + level 1 tuner fills the level nicely up to 9, and if you use Tunermorph last, the opponent can’t do anything about the impending Quarion!
Crystron Ametrix + 1 + Crystron Rion = Crystron Quariongandrax Another way to get the boss out! Usually not as good because there is no floating involved when you Synchro summon with Ametrix! Both of above mentioned combos can be used with Crystron Sulfefnir instead!
Playing with this skill will help you realize a lot more possible plays, so don’t be afraid to experiment!
Crystron Entry can change the level of any of your Crystron monster by sending a Crystron monster with another level from your deck to the graveyard. You can use this effect to adjust the levels of your monster you control, or you can mill monsters such as Rosenix, Prasiortle, or Sulfefnir for their own effects, regardless of level changing.
You can use Level manipulation skills alongside Entry to help in summoning of your Synchro monsters! Unlike with skills, your opponent can respond to the activation of the Entry in your graveyard!
Entry can also be used as pseudo - Foolish Burial to send monsters whose effects you need to use. For example, if you send Smiger with Entry, you can search your deck for another Entry, or if your Sulfefnir got banished, you can send another one via Entry so your plays can keep going! Another way you can use Entry is altering the levels of your tuners on your opponent’s turn!
We’ll show that use in following example:
We have Rion on the field, Entry in the graveyard and Smiger in the banish zone. During the opponent’s turn, when we activate Rion’s effect we can chain Entry from the graveyard and change the level of Rion to 2 by sending Crystron Prasiortle or Crystron Citree, so instead of Powered Inzektron we get Synchro summon Crystron Ametrix with Smiger! You can also do the same thing with Citree!
Let’s consider another situation.
We have Citree on the field, Entry and Prasiortle in the graveyard. We won’t get prompted to summon anything because there are no level 4 Synchro machines in the Duel Links!! We can play around that with the toggle button. During the main phase or battle phase of opponent’s turn, if we switch toggle to ON we can use Entry from the graveyard to change Citree to level 3 instead, by sending the Smiger or Rion to the graveyard. After the effect of Entry resolves, you can immediately perform Synchro summon by using the Citree and Prasiortle to make Crystron Ametrix!
Entry has usage even after you finish with your Synchro plays:
Let’s say we already summoned Quariongandrax, we have Entry in the graveyard and we have a Smiger in the hand. We also used up our normal summon. We cleared the board, but we would miss the lethal damage by 1000. Since we have Entry in the graveyard, we can use it to send Prasiortle to the graveyard and use its effect to special summon Crystron monster for our hand for lethal damage! You can also use the Smiger to destroy Quariongandrax and special summon any banished monster, including your opponent’s!
If you are afraid of Sealed Tombs -induced OTK, you want to setup a Rion play by sending the non-tuners to the graveyard(either with Scrap Recycler or Crystron Sulfefnir)and using their effects to get them to banish pile. After that, all of the Rion summons can help prevent the OTK.
Scrap Recycler + any Crystron card + World Legacy Clash This one is a bit technical. First you summon Scrap Recycler and mill Sulfefnir. Then you special summon Sulfefnir and destroy itself to summon any of the Crystron non-tuners. For this example, we will summon Crystron Smiger for future plays. Then we use the Smiger’s effect to destroy itself and summon Rion from the deck. Then we set the World Legacy Clash and end the turn. The technical part comes into the play during the opponent’s turn. Let’s say they use Sealed Tombs right away. If they summon anything to try and finish you off while under the effect of the skill, you can use your set Clash in response to any effect. We called this one “technical” because World Legacy Clash banishes as a cost! In other words, you banish the monster as soon as you activate the card! So if they summon Snipe Hunter and try to destroy your Rion, you can chain your Clash to remove Scrap Recycler from play and immediately after that, Synchro summon using the Rion’s effect and newly banished Scrap Recycler. This play is, however, vulnerable to Cosmic Cyclone while they have no monsters face-up. It’s important to remember, if they go to the battle phase and your toggle is set on AUTO, World Legacy Clash will prompt you to active it IN DAMAGE STEP! You cannot special summon during the damage step, unless stated otherwise on the card!
Important note: the turn player has priority! You CAN NOT Synchro summon during the opponent’s main phase before they do anything, even if you have your toggle set to ON! Turn priority is very important because opponent can use Sealed Tombs before you get a chance to do anything. However, if they make any play before they use the Sealed Tombs, you can still use Citree’s effect to make a play. For example, if opponent normal summons Snipe Hunter without using the skill, you can use Crystron Citree and Crystron Rosenix to make Powered Inzektron. After that, you are safe from the Tombs and you have Rosenix banished, meaning you now have setup for Rion if you need to survive it in later turns!
Darklords are one of the worst matchups for Crystrons. They swarm the board with big bodies that are hard to run over without Beatdown. Darklords also posses the ability to negate monster effects on field by employing the searchable trap: The Sanctified Darklord. The trap doesn't target so you don't know what they are gonna negate until the trap's effect resolves. They can chain this effect to Crystron Quariongandrax and Black Rose Dragon which makes it hard to clear their field if they have the trap on field or in graveyard. This can be avoided by using World Legacy Clash to "dodge" the negate and reduce the potential healing they would get from Sanctified. New Synchro we got helps dramatically in Darklord matchup. If you have Crystron Citree on the field and Crystron Sulfefnir in the graveyard, you can activate Citree to try and summon Sulfefnir for Synchro summon of Samurai Destroyer and chain World Legacy Clash to remove Citree from the field if they try to negate Citree. This leaves Sulfefnir on field which is going to float upon destruction which massively boosts your chances of survival. Another thing too keep in mind is White Aura Dolphin, which Darklords can deal with only with Darklord Desire. Once Desire is dealt with, Dolphin's attack halving and revival make quite a nusiance to deal with. Tech options to consider for this matchup:
Invoked neos is a very tough matchup for many reasons. Invoked Cocytus is very tough for us to deal with without the right setup, especially with Aleister the Invoker boosting its stats. Also, the summon of Cocytus inculdes banishing a water monster from either players grave, so they can easily banish our important water monsters in the GY such as Sulfefnir, or they can banish Scrap Recycler to make Invoked Magellanica which is also a problem with its 3300 defense, we need spells and traps to take care of it. Neos Fusion protecting Brave Neos is also annoying for us, especially when paired with Beatdown as it lets them survive their attacks and then beat over our monsters. Last but not least, many of them side deck Lava Golem which can mess our strategy up. Now that we have all the threats down, lets start talking about how to deal with them. If you only have one WATER monster in the Graveyard, chain your Citree's effect to summon the WATER monster which will either make invocation fizzle out or force the player to use his own monsters as materials. Chaining Cosmic Cyclone to Invocation is also a rather strong play a they cannot add the banished Aleister to had, nor can they ever use Invocation for the rest of the duel, leaiding to less Cocytus to deal with. When trying to deal with an on-field Cocytus, Samurai Destroyer is your best friend. He makes it so Aleister needs to use his effect at the start of the battle phase if he wants to get the boost. On your opponenets turn, he can also mistakenly activate Aleister early to trh to beat over Samurai with Cocytus, only to realize that Samurai Destroyer will negate his effect and just cancel the attack. Most importantly, when Samurai Destroyer attacks, he will stop Cocytus's effect that prevents it from being targetted or destroyed by effects, so you can attack with Samurai Destroyer and then activate Enemy Controller or World Legacy Clash to beat over the Cocytus. Remember to not banish Samurai Destroyer with Clash as hell no longer be on field, and Cocytus will gain its retargetability back. A good strategy is to try to deal with the Brave Neos's and Flip Flop Frogs first and then deal with Cocytus later, as Cocytus is not as big of a threat with its significantly smaller attack. Dealing with Magellanica and Lava Golem is straightforward. Magellanica is just a big beater, we need to use our tech cards to deal with it. When it comes to lava golem, obviously try to keep one monster on the field, although this is easier said than done. If you have to commit more than one monster to the board, try to ensure that you have a follow up play such as Scrap Recycler or Sulfefnir in hand, so you can come back from a lava golem. Overall, this is a very tough matchup for crystrons, so dont be surprised if you end up losing to them more often than not.
Slightly annoying matchup because of the disruptive backrow, you usually have the resources to outplay them. The other annoying part is Triamid Kingolem which will stop floating of your monsters, if they are attacking into you. The other card to watch out for is Triamid Fortress which prevents the effect destruction. The backrow is your friend in this matchup, because it can help you grind out their traps, which they usually play the least amount of. The other way you can deal with them is nuking the field with Black Rose Dragon, if you have the follow up after it. When Triamids lose their field spell, they get slowed down dramatically, which in turn lets you go ham with Crystron Quariongandrax and White Aura Dolphin. Side note, if you use Cosmic Cyclone on their field spell during your turn, they can chain monster effects to swap it, so you either want to do it in their battle/end phase, chain it to the monster effect or use cosmic on their backrow(which is the best option most of the time). The most useful cards for the matchup: Cosmic Cyclone , World Legacy Clash and Treacherous Trap Hole.
This deck does fairly well vs Desperado Barrel Dragon, since it has many floating effects. When you know you are vs Desperado, you should try to aim for making an early White Aura Dolphin, or in mid to Late game, try to make Quariongandrax, as his effect will not let your opponent summon Desperado, so you will be able to clear the field and swing for lethal. Crystron Ametrix is also good as Desperado or Blast Spider destroying it will allow you to float into more monsters to make it easier to summon the key synchros.
Against the Cyberdark Variant, Dolphin+any other synchro is lethal over a Cyberdark Edge equipped with Cyberdark Cannon or Leng Ling, as the equip gets destroyed first. Edge is always a liability for them, as with Burei and Dolphin, it can become a portal to their life points for us. IF you know the Cyberdark player is not playing Desperado, make sure to watch out for Lava Golem, although it is not that big of a threat as you can destroy it with any of your non-tuners.
Neos Variants are also very susceptible to Quariongandrax removal.
Usually a favorable matchup, Ancient Gears can sometimes make your day worse with their backrow. If they are running Double Cyclone, this matchup becomes even easier because you don’t need to set spells or traps at all. You can also get tuners out without needing to use normal summon, thus avoiding adding counters onto Ancient Gear Castle. The main threat ancient gears possess is a huge beast, Ancient Gear Reactor Dragon which they can either normal or special summon. Depending on the way it was summoned, you can switch it to defense with either Ametrix or Burei, and proceed to go crazy with your other Synchro monsters. Beatdown greatly helps in this matchup, because any 2 Synchro monsters boosted with the skill can destroy the defense position Reactor Dragon. However, if they get a massive field, you can punish it with either Black Rose Dragon or with Quariongandrax. Quarion can be a massive problem for their resources, because they usually play only 2 Reactor Dragons and have no way to recover them from banish pile. Cosmic Cyclones can also be very helpful in this matchup. Side note, if you banish the Reactor, you can destroy your own Quariongandrax to “steal it”, as it has no special summon restrictions, and it plays around potential Drowning Mirror Force!
Since Blue Eyes decks focus on destroying your monsters by battle with special summoned monsters, it is a relatively easy matchup for us. The trickiest thing about this matchup is Sealed Tombs, which is discussed briefly above before. However, if you have a solid hand, you can go into Citree to bait out their Sealed Tombs, and then later in the duel, Synchro summon White Aura Dolphin, as Blue Eyes only way of dealing with Dolphin is killing it while under Sealed Tombs. If you can do that, you should be smooth sailing. In addition, as long as you can survive the Sealed Tombs, you can simply go into another Citree and there is not much they can do about it. Pulse Mines also greatly help in surviving a Sealed Tombs turn, making the matchup a lot smoother. As a bonus note. If you run Burei, you can flip their The White Stone of Ancients into attack for massive damage!
Spellbooks is a gritty matchup. Try not to make too many Synchros until you have grinded through their Fates, as they are often forced to use Spellbook of Fate on your citrees. Once they burn through two Fates, they start to lose steam, and that is you time to strike, making Synchros to overwhelm them. Having Scrap Recycler is also very helpful in this match up as he leads to more overall board presence, and Spellbooks have a problem dealing with more than one big monster at a time. To win the matchup, you have to be more patient than usual. Drawing your backrow also help! If you use Treacherous Trap Hole or Enemy Controller on the first monster they summon, they won’t be able to use most of the Spellbook cards, since they don’t have a face-up spellcaster-type monster. After you stop their turn, you can usually finish them during the next turn. Important note, if your toggle is set to AUTO, you won’t get prompted to use Treacherous Trap Hole if they set their monster! If you are using World Legacy Clash, you can save your Citrees from banishment!
Magnets are another gritty matchup. Magnet Warriors spam the board with small monsters, neither of which can deal with Ametrix on their own. They need to either use traps like Triamid Pulse or Treacherous Trap Hole to get rid of it, but that allows further floating. Their smaller monsters also can tribute themselves to summon Delta The Magnet Warrior, thus avoiding the potential destruction or banishing. However, you can still clear the board with Black Rose Dragon if they get too much advantage. Other way they can deal with our Synchros is their boss monster. Boss monster of Magnets is Berserkion the Electromagna Warrior, which banishes a Magnet Warrior from the grave to pop a card on the field. Since it is targeted destruction, our tuners can evade the effect, and our Synchros can float until they are all out of fuel for Berserkion, and then it is easier to deal with them. Block Dragon is another boss monster of theirs, which can be difficult to out without a World Legacy Clash, since it protects from destruction. However, with beatdown we can easily get over its 2500 attack, and if they try to wall off by placing it in defense, try to make Burei to change him into attack position. This matchup can become a lot hard if they are playing a version with That Grass Looks Greener which can allow them to gain a lot more advantage. All in all, you want to get Ametrix out as soon as possible, float into your safety and not overextend. Wait for them to make a big push, and punish on your turn. White Aura Dolphin can help in the late game, but you have to consider the number of destructions Berserkion can do! Overall, not an easy matchup, but you need to be patient.
Six Samurai can go either way for this deck, but it is usually in our favor, especially with only one Legendary Six Samurai - Enishi. Legendary Six Samurai - Shi En is not a big threat for this deck as we mainly rely on our monster effects. A big part of this matchup is using Burei and Ametrix’ effects to change their monsters to defense and shut off Six Style - Dual Wield, as without Dual Wield, Six Samurai lose a lot of strength in this matchup. World Legacy Clash can be problematic but if they use Clash on Ametrix you get to float so it isn’t too detrimental. Quarion is also a large help here as other than Dual Wield, they have no real disruption, so you can wipe their board. It is advised to not make Quarion if you suspect they have a world legacy clash set, as it can dodge Quarions effect. However, if you have a non tuner that you can get onto the field, you can destroy the recently Clashed Quarion to special summon the monster that they banished with world legacy clash. Quarion also removes resources from their graveyard, so they need to make additional effort to use Enishi’s bounce effect.
Subterrors have been popping up lately, mainly as a counter strategy, since their main skill got nerfed, so now they abuse Labyrinth Builder to cheese out summons with Subterror Nemesis Warrior. If they start the game with both Nemesis Warrior and Subterror Final Battle, things can get tricky, but if you manage to get out a Black Rose Dragon after the usage of Lab Builder, you win 90% of the time, since its drawback is hard to recover from. Sometimes they use Neos Fusion to send Nemesis Warrior to the graveyard, but getting rid of Elemental HERO Brave Neos and their graveyard resources is pretty easy with Quariongandrax. Level Augmentation helps a lot in this matchup and makes it very easy. Generic backrow also helps lessen the trouble they might cause. Overall, slightly annoying matchup, but not a difficult one.
Vendread is the newly added zombie-ritual archetype to the duel links, and it’s still being optimized. At first glance, the effect to banish monsters during either player’s turn seems scary, but it actually requires a fair amount of setup to pull it off. Mainly, they need to summon Vendread Revenants to the field and then ritual summon using those revenants to gain the effect. This effect seems strong in theory, but it has its downsides. It only banishes special summoned monsters, and this deck normal summons pretty often. Other downside they have is the whooping 0 defense they have so even puny Scrap Recycler can run it over with his small wheels. You can put them into defense with multiple ways: Pulse Mines, Crystron Ametrix, Enemy Controller, or you can use Drowning Mirror Force to ruin their day. However they can also setup the banish of the spells/traps with Vendread Houndhorde so you have to be careful about that. The matchup gets more difficult if they play Master of Rites II which prevents your monster from targeting them, but you can either turn them into defense without targeting, or beat over them with synchros if they don’t have the Revenants effect ready. Overall, not the easiest matchup, but it requires you to play more conservatively than usual.
Mirror Mirror on the wall whos the best crystron player of them all? In the mirror match you want to let your opponent synchro summon first so you can then Ametrix them and kill. It is hard to write a complacent guide for the mirror as everything is up to board state. However, it is notable that this decks only way of dealing with a White Aura Dolphin is Quariongandrax, so it can be a solid win condition here. As with almost all mirrors, Enemy Controller is an amazing card as you can steal your opponent's monsters and use their effects.
I try to post replays as often as I can on my YouTube channel for this guide, if you would like to see any replays, please ask the experts and we’ll get some for you! <3
This deck has a lot of potential especially as more and more powerful machine type synchros get added to the game, and it has a unique mechanic that makes them fun and satisfying to play.
That is all for now! We’ll keep working on improving and expanding the guide, If you have any questions, feel free to stop by the Crystron channel in DLM discord and ask away!
Everyone in the Crystron channel at DLM, especially Dulling for introducing me to the deck!
