Dinos were one of the first meta decks, and also had a time where they were tier 3 due to the addition of Evilswarm Salamandra before falling off again. Now, with the recent Tyranno Hassleberry event the deck received a new support card called Survival's End (SE), making them tier worthy again. In addition to that, they also received the card Giant Rex from an older Hassleberry event which has perfect synergy with Salamandra's banish effect. Their main strategy is to set up a SE as soon as possible with cards like Paleozoic Marrella to then destroy your own dinos and especially big monsters from the opponent. A good dino monster that has synergy is Babycerasaurus because when he gets destroyed by card effect you can summon a dino from your deck. Overall the deck likes to set up slowly, destroy the opponents field, and then swarm with many dinos from the deck.
Mind Scan - Mind Scan is a nice skill to use when you want to see if the opponents has some battle traps like Wall of Disruption or Drowning Mirror Force. The deck is really week against such cards, especially focusing on destroying an opponent's big beaters with your SE.
Unstoppable Dino Power - This skill is good to use in the mirror match because you canpush your own dinos over theirs with a permanent boost of 100 atk, but it is not very useful against matchups like Koa'ki Meiru, because boosting your Evilswarm Salamandra to 1950 atk is not enough to get over a Koa'ki Meiru Urnknight.
Dinosaur Kingdom - Pretty much the most used skill due to the 300 atk boost, which gives your Evilswarm Salamandra or your Giant Rex the opportunity to get over big boss monsters like a Koa'ki Meiru Maximus in defense position or a Laval Stennon. The attack boost of the field spell is also nice because your normal summoned dino often be bigger than another normal summoned monster from your opponent.
Giant Rex (1x)Survival's End because you can just re-summon him again with the banishing effect of Evilswarm Salamandra.
Evilswarm Salamandra (2-3x)Dinosaur Kingdom. By banishing Giant Rex with Salamandra's effect, you can re-summon him. For example, Salamandra's effect cam be activated after using your Giant Rex to use Survival's End's grave effect or if your Giant Rex is destroyed by battle or card effect.
Babycerasaurus (2x)Survival's End, but if you only play 1 Babycerasaurus you pretty much have no monsters left in deck that you can summon. Monsters you summon with SE get destroyed in the end phase you summoned them, so the main usage of this card is it to summon your big dinosaur monsters from your deck by destroying him with the grave effect of SE so you don't go -1.
Survival's End (3x)Paleozoic Canadia because it counts as a normal monster while on the field. The main monsters you would like to summon off of this effect are Giant Rex and Babycerasaurus because you can use them in the same turn to destroy something on the field. Also important to notice is that when you have some Paleozoic monsters on the field, you can destroy them with your SE to summon a few dinos from the deck and go for game. But now we come to the major part of why this card is so good and makes dinos relevant again. The grave effect says that you can destroy 1 dinosaur monster you control to target and destroy 1 card your opponent controls. This effect gives dinos a good disruption during the opponent's turn, especially when you go first and are able to set up a SE before they summon a monster.
Paleozoic Marrella (3x)
Skull MeisterAncient Gear Reactor Dragon, you can use your Skull Meister in your hand to negate the effect of the card and prevent your opponent from summoning a Reactor Dragon. But not only is this card good against AG, it is also good in the mirror match because there it is a coin flip who goes first and can set up the SE in the grave. Skull Meister plays a major role in this situation because you don't your opponent to destroy your cards before you were able to set up a SE in the grave. In addition, you can stop an opponent's SE in the grave with this card.
Floodgate Trap Hole
SabersaurusMegalosmasher X because he has second highest attack of all dinosaur type monsters.
Dino (Mirror Match)
The mirror match is somewhat coin flip dependent. The person who starts has the advantage to set up their SE and canadias first. Also important is that you don't want to activate your SE first. This means that you shouldn't summon any paleos or normal monsters except when your SE is live and maybe if you already have a second SE ready to activate. The person who activates SE as chain link 2 is able to destroy the monsters and summon dinos from the deck, but be sure to not summon any normal monsters from your deck in this scenario - When you special summon a normal dino from the deck, your opponent will then destroy the normal monster you summoned and in turn special summon a dino from their deck. So in the mirror match you should not summon a normal monster when you go second and your opponent has backrow on the field, and instead try to force your opponent to activate his SE first.
This matchup is not that hard when you can set up a lot of SE in the grave as soon as possible, but Ancient Gear Fortress prevents you from destroying their Ancient Gear monsters on the turn they are summoned. If your opponent tries to destroy their own Geartown with a Breaker the Magical Warrior or Galaxy Cyclone, you can easily make it miss the timing by using a SE from the graveyard.
One of the easier matchups I would say, because normally they can only get over your dinos with Masked HERO Anki, but if they play Destiny Calling they are able to get over your dinos. Your main focus of cards to destroy with SE is on the Anki and their field spell. But you should also be aware of their backrow, especially when they play Wall of Disruption because this card could literally end the game for you due to not having any backrow hate in the deck. Check for delays before you attack to play around this.
This matchup is partly good but also partly bad, especially when the Karakuri player is able to set up multiple Karakuri Anatomy on turn first turn. The card advantage they can get could be very difficult to deal with, especially when they have multiple Offerings to the Doomed to destroy your normal summoned monsters. In this matchup, your main focus of cards to destroy with SE is on their synchro monsters, as their other monsters cannot really get over your dinos.
Koa'ki Meiru is one of the hardest matchups because of Diamond Core of Koa'ki Meiru protecting the opponent's monsters from getting destroyed by SE. Play around this by using your Paleozoic Canadias on the opposing Koa'ki Meiru Urnknight and Koa'ki Meiru Maximus, because Urnknight can summon a Sandman from the deck which can negate the Canadia. The main focus of cards to destroy with SE in this matchup is the Maximus, either on your turn if they open with a Diamond Core, or on your opponent's turn because Sandman cannot negate SE in the grave.
This is also a very hard matchup. Due to playing so many traps, Amazoness decks can easily stall out the game. Floodgate Trap Hole and Paleozoic Canadia prevent you from using your SE in the grave, because your dinos have to be face-up on the field in order to activate the effect. The main focus here is to destroy the opponent's Amazoness Queen and Amazoness Onslaught with SE.
In this matchup, you should destroy their Laval Cannon before they can synchro summon into a Laval Stennon because this synchro can banish 1 laval monster to negate all the cards that target it, making it immune to SE. Using Dinosaur Kingdom in this matchup is extremely useful, because Laval Stennon has only 2700 atk which can easily be beat over with Evilswarm Salamandra by banishing 2 monsters from the graveyard. Your main focus of cards to destroy with SE is on either their tuner or their Laval Cannon, but also be aware of the destructive power of the card Dustflame Blast, because this card can pretty much be a whole boardwipe. To counter this, summon or set a Babycerasaurus so you can have at least one dino monster on the field after they use the card.
When you have a SE on the field and one SE in the grave be sure to activate the SE in the grave first, so you can target 2 cards you wanna destroy and than chain the SE on the field to destroy the normal monsters on the field to summon a few dinos from the deck.
If you play against AG and the opponent wants to attack with a Reactor Dragon while you have a normal monster on the field and a SE set face-down, you have to set your toggle button to ON to chain the grave effect of SE on the effect of special summoning a dino from the deck and destroy the Reactor Dragon before he attacks.
SE in the grave can be activated even if a Reactor Dragon attacks.
When your opponent declares an attack with an Ancient Gear Wyvern and you have a Babycerasaurus on the field and a SE in the grave, you have to activate the SE in the grave before the attack because when you chain the SE in the grave to the attack of Wyvern you won't be able to special summon a dino from the deck with the effect of Babycerasaurus.
When you open with a Paleozoic Marrella you want to activate him in your opponent's draw phase by setting your toggle button to ON so you can set up a SE in the grave very quickly, but you should only do this when you also open with a dinosaur monster.
If you go second in the mirror match and open with a normal type monster it would be better to set it. If you summon it, your opponent can potentially use SE to destroy your monster and summon a dino from their deck.
You can use a SE in the grave on a Citadel Whale and he cannot negate it - the card says that "when one of your water typer monsters and no other card is targeted," but SE also targets your own dinosaur monster.
Another thing that you should do when you banish a Giant Rex with your Evilswarm Salamandra is to banish another dino from the grave first, so that Giant Rex gains 200 atk when summoned. This doesn't sound very important, but it could be crucial in the mirror match.
The last tip I can give you is to not overcommit with your SE in the grave so use them wisely and only destroy cards that are problems for you like a Ancient Gear Reactor Dragon, which you cannot destroy by battle because none of your monsters has enough atk to get over him.
Dinos is a deck that has good beaters especially with the boost of the field spell and they have a good card to disrupt the opponent during his turn with SE. This deck will find its place in the meta as one of the mid tier decks due to not having a real boss monster with a high attack. It has some weaknesses to decks that stall or to many cards such as Floodgate Trap Hole and Paleozoic Canadia which prevents you from using your SE in the grave. Eventhough it doesn't have too many destruction effects it has a good matchup against a big variety of decks if you use your SE wisely.
