What Fish OTK seeks to do:
- Kill you with the Colossal Fighter + Armory Arm OTK if you have a face up monster with sufficient attack. Armory Arm is equipped onto your strong monster, and from there Colossal Fighter repeatedly suicides and revives itself in battle. Burn damage is inflicted to the opponent from Armory Arm's effect, while you yourself take minimal battle damage from the battles involving Colossal Fighter.
- Kill you with the Brionac combo (Sea Dragon Lord Gishilnodon + Coelacanth + Brionac) if you have a set monster, or a monster in defense position. Gishilnodon will have 3000 atk, Coelacanth has 2800, and Brionac has 2300, which stacks up to 8100 total.
What the deck looks like:
- Similar to the Formula Frog Monarch deck, Fish OTK relies on the frog engine for tribute fodder. This is comprised of multiple copies of Treeborn Frog, Swap Frog, and Ronintoadin. The deck can also play Dupe Frogs and Snowman Eaters.
- The OTK enabler is
SeakingSuper Ancient Deep Sea Coelacanth. The goal is to bring out 2 copies of Oyster Meister and 2 copies of Fishborg Blaster with the Coelacanth's effect.
- The deck can run either no traps, or multiple copies of Spiritual Water Art Aoi, which tributes a water monster to strip a card from the opponent's hand. It's especially profitable to tribute off an Oyster Meister, which then generates a token for you to block attacks with, or use as synchro material.
What are the decks weaknesses:
- Much like Formula Frog Monarchs, the deck revolves around the Frog engine. Removing Treeborn Frogs and Ronintoadins from play can cripple their strategy.
- If you're able to stop their OTK push somehow, it's likely they won't have the resources to push again on their next turn, giving you an opening for a counterattack while they try to set up again.
- While not inherently a weakness, they have only two cards with which to ensure the safety of their combos, which are Giant Trunade and Cold Wave. It's too risky for your opponent to perform the combo when you have live backrows.
- They have a hard time getting over Naturia Beast and its effect. If you can get it out and protect it, it's usually game over for your opponent.
What you can side in against Fish OTK: (depends on your own deck)
- DD Crow
- Effect Veiler
- Chain Disappearance
- Dimensional Fissure
- Fossil Dyna Pachycephalo
- Skill Drain
- Dark Bribe
While it is good and all that you'll be removing from play their tribute fodder, obviously the Fish OTK player isn't dumb, and will side in the single permitted copy of Burial From The Different Dimension to counteract that. Still, DD Crow and Effect Veiler are very crucial cards, especially Effect Veiler. I listed Dark Bribe only because you'll be aiming to negate the game-breaking Giant Trunade or Cold Wave. Also bear in mind that Fish OTK players will be siding in copies of Malevolent Catastrophe to punish those who set heavy backrows recklessly.
You'll be dropping the Effect Veiler to negate different monsters depending on which combo your opponent seeks to unleash on you. It's unwise to Veiler the Coelacanth, since your opponent will still have their Fishborgs and Oyster Meisters in their deck to bring out on their next turn. It'll be more difficult for your opponent to recover if you instead get rid of the key players in the two OTK variations, being Armory Arm and Brionac.
- Colossal Fighter + Armory Arm combo: Play Effect Veiler on the Armory Arm, so that it cannot equip itself.
- Brionac combo: Play Effect Veiler on the Brionac, so that it can't bounce your monster(s).
