What are the Ojamas?
Ojamas are an archetype used by Chazz Princeton in Yugioh GX along with the Armed Dragon LV monsters and the VWXYZ machine monsters (V-Tiger Jet, W-Wing Catapult,X-Head Cannon, Y-Dragon Head, Z-Metal Tank, and the respective contact fusions). For years these archetypes had no synergy but thanks to the cards Ojamatch and Ojamassimilation they make quite a functional deck in Duel Links using Ojamas, Armed Dragons, and the XYZ machine monsters.
How do you use Ojamas?
Their playstyle can vary but for this guide the Ojamas are used for their search power via Ojama Blue and for their ties to the Armed Dragon LV monsters (via Ojamatch)/XYZ machine monsters (via Ojamassimilation).
Why use Armed Dragons?
Armed Dragons give the deck a lot of utility as well as being able to search out Ojama Blue via the card Ojamatch.
Why use the XYZ machine monsters?
They give the deck a very powerful win condition in the form of XYZ-Dragon Cannon (via Ojamassimilation)
Why not the VW machine monsters?
These monsters don’t do enough to warrant space in the deck unfortunately and are better used as slots for other cards.
Why play this deck?
I can’t speak for others but I do find this deck to be pretty enjoyable to play, has a surprising amount of power that allows it to go toe-to-toe with even meta decks, and perhaps simply for the memes.
The Game Plan
This deck’s win condition is to use Ojamassimilation to bring out XYZ-Dragon Cannon and use its non-once-per-turn destruction effect to wipe the opponent’s board. Following up with Armed Dragon LV3 results in an OTK. Ojamatch is used to cycle through the deck and put out an Armed Dragon LV3 that is used to special summon Armed Dragon LV5 if desired. While putting Armed Dragon LV5 on the field is not always optimal (if you don’t have one of the XYZ-pieces in hand you won’t be able to make XYZ-Dragon Cannon if Armed Dragon LV5 is still on the field when Ojamassimilation is used), Armed Dragon LV5 is useful for being a 2400 Atk body, having spot removal via its own effect, and can be returned to the hand by A Wingbeat of Giant Dragon to destroy all spell/traps on the field. Union Scramble is good recovery/OTK enabler after XYZ-Dragon Cannon has successfully been summoned. The skill Land of the Ojamas is useful since Ojama Country can be sent off Ojamatch to search out Ojama Blue. Ojama Country is also useful for reviving Ojama Blue, swapping Atk/def, and making it easier for Armed Dragon LV5 to destroy certain monsters using its effect. Sphere Kuriboh/Enemy Controller are good to prevent OTKs.
One of the key pieces of the deck, Ojama Blue allows the player to search 2 ‘Ojama’ cards when destroyed by battle. Ojama Blue serves as a quick way to get to the win condition, Ojamassimilation, and can also search out Ojamatch and any Ojama Monster that can be used for Ojamatch/Ojamassimilation.
Another key piece of the deck, Ojamatch allows the user to search out an Armed Dragon Monster and an Ojama Monster (Usually Blue) and normal summon one of them. Keep in mind that it is a quick-play spell, which allows a lot of flexibility. Normal summoning Armed Dragon LV3 in the standby phase off Ojamatch allows LV3 to level up into LV5. Can be used to shuffle back 3 banished Ojamas for a draw.
I find two of each of Armed Dragon LV3 and LV5 to be a good ratio, but I have seen 1 Armed Dragon LV3 and 3 Armed Dragon LV5s. A single copy of one of them would mean that you can’t search it off Ojamatch if it is currently in hand.
These machine monsters are used to make the fusions and can serve as beaters in a pinch. Should be noted that Y and Z can equip themselves to another piece to free up a zone (this is useful for allowing the third piece to come into play to make XYZ-Dragon Cannon).
I recommend one to two Normal Ojamas (with different names if running more than one). The reason for different names is that Ojamatch must search a Ojama Card with a different name. Thus, if you pitched Ojama Black for the cost of Ojamatch, you could not search another Ojama Black.
This is the heart of the deck and is what will be used to win most games won. This allows the player to summon the XYZ pieces by banishing the Ojama Monsters from hand, field, or graveyard. The XYZ pieces can then be contacted fused into the XYZ fusion monsters by banishing them. Can be banished from the grave to put 3 banished Ojamas back into the deck for a draw. Keep in mind that currently this card is only one per account and you must make it count when you use it.
The main boss monster that you go into off Ojamassimilation. It can destroy 1 card on field by discarding 1 card and is not once per turn. Use this to wipe the opponent’s board and OTK with the assistance of Armed Dragon LV3. Note: If not using a card like Union Scramble, you will only be able to make XYZ-Dragon Cannon once during a duel. This means that you only need one copy if not using a card like Union Scramble.
This two-piece fusion can pop face-up spell/traps by discarding 1 card. Rarely comes up but might as well have it as an option.
This two-piece fusion can pop set monsters by discarding 1 card. Sometimes comes up and proves to be useful.
This is probably the best two-piece fusion as it can pop set cards by discarding 1 card and has the best stats among the two-piece fusions at 2400 Atk.
This card can be used to destroy all spell/traps on the field by returning Armed Dragon LV5 to the hand. Very good way to secure Ojamassimilation going through and can sometimes be a blowout.
This is best option to recover if XYZ-Dragon is answered as the monster cannot be revived from the graveyard. Union Scramble lets you summon the banished materials back and make another contact fusion. It can also be banished to add on the banished materials back to the hand. This works well for Treacherous Trap Hole as it removes itself from the graveyard.
2400 Atk body that prevents traps cards and is relatively easy to summon thanks to Ojamatch and Ojama Country being able to revive an Ojama.
Give the deck disruption and thanks to Ojama Blue’s searching effect, the skipping your draw phase part can be mitigated.
A cute optional one of that prevent players from playing effect monsters until your next turn. It must be activated at the start of main phase one but thanks to Ojamatch, you can summon Armed Dragons in the standby phase before activating Heat Wave.
This is more of a side-deck card, but this card allows you to return all level 7 or higher monsters to the hand by tributing one of your face-up attack position Ojamas.
These match-ups can be hard if not running cards to prevent an OTK. Destiny HERO - Drilldark + Masked HERO Anki will lead to an OTK if they attack over a face-down Ojama Blue while Ojama Country is in play. For that reason, playing Ojama Blue in face-up attack position is sometimes the correct play. Vampires destroying Ojama Blue by card effect instead of by battle can prove very problematic as you will not get to search.
Probably your hardest match-up as Silent Magician’s spell negation and Spellbook of Fate are very good against XYZ-Ojamas. XYZ-Dragon Cannon is the main out to Silent Magician LV8. Union Scramble can be very helpful for this match-up.
You usually want to build a board, so you don’t get OTK’d going first or second. If Ojama Blue is destroyed by battle, you can normally win.
Gladiator Beast/Back-row decks
XYZ-Ojamas usually have a strong match-up against Gladiator Beasts. You can sit on Armed Dragon LV5s and them attacking Ojama Blue plays right into your game plan. You have a very good match-up against Gladiator beasts/back-row decks if running A Wingbeat of Giant Dragon or Jinzo.
Side Decking Recommendations
Here I list options for cards that can be sided against given match-ups using a 5-card side deck. I recommend siding the cards that are good in these match-ups that are not covered by the main deck being used.
Against Heroes / Vampires
If worried about being OTK’d:
If worried about back-row:
Note: I am usually more concerned about being OTK’d in these match-ups than being stopped by back-row but use your own judgement in a given match as back-row can hurt too.
Against Gladiator Beasts/Heavy Backrow Decks:
Note: A Major Upset is there to out Silent Magician LV8.
The reason why this deck works in theory is that it only needs to either see Ojama Blue or Ojamatch to get its plays going. This has about a 79% chance to occur going first and an 87% chance to occur going second. Ojamassimilation is an excellent win condition as thanks to cards like Ojama Blue, you will usually have plenty of cards in hand to wipe the opponent’s board with XYZ-Dragon Cannon.
Some Neat Tricks
Summoning Multiple Armed Dragon LV5s off 1 Armed Dragon LV3: This play involves using at least 2 Ojamatches. Use 1 Ojamatch in the standby phase to bring Out Armed Dragon LVL 3 (don’t chain the other Ojamatches), use it to bring out LVL 5, then use the other Ojamatch to bring back the Armed Dragon LVL 3 and use it to bring back another LVL 5. Tip: Plan the Ojama searches ahead because you normally want to end with an Ojama Blue in hand after this play.
Battle Phase looping: This play involves using Ojamatches to loop an Armed Dragon LV5 with another Armed Dragon LV5 in the battle phase by searching each other out and normal summoning over each other. Since the Armed Dragon LV5s were summoned in the battle phase, they can attack.
Securing the Wingbeat: This play comes up when you use Wingbeat of Giant Dragon to bounce LV5 but your opponent chains something to prevent the Armed Dragon LV5 from returning to the hand. You can chain Ojamatch to search the other Armed Dragon LV5 and summon it over the first one. This allows the new Armed Dragon LV5 to be returned to the hand to destroy all spell/traps.
Crashing Ojama Blue
While this usually doesn’t seem like a good idea, sometimes crashing Ojama Blue is the correct play (this can allow the player to search out two Ojamatches and possibly clear some threats with them in the battle phase).
