Fish OTK
I decided to do my article this week on a very consistent OTK deck that has been flying under the radar for several weeks now; Fish OTK. The basic way this deck wins is by summoning Super Ancient Deepsea King Coelacanth. He allows you to summon as many other fish monsters as possible from your deck just by discarding one card. From there, there are various combos where you can deal over 8000 damage to the opponent. Here is my build for Fish OTK:
Monsters: 23
3 Superancient Deepsea King Coelacanth
3 Swap Frog
3 Fishborg Blaster
3 Oyster Meister
3 Dupe Frog
2 Snowman Eater
2 Treeborn Frog
2 Light and Darkness Dragon
1 Ronintoadin
1 Gorz the Emissary of Darkness
Spells: 17
3 Moray of Greed
3 Pot of Duality
3 Enemy Controller
2 Mystical Space Typhoon
2 Gold Sarcophagus
1 Lance
1 Giant Trunade
1 Monster Reborn
1 Dark Hole
Extra Deck: 15
2 Armory Arm
1 Colossal Fighter
3 Formula Synchron
1 Sea Dragon Lord Gishilnodon
1 Brionac, Dragon of the Ice Barrier
1 Goyo Guardian
1 Stardust Dragon
1 Scrap Dragon
1 Ally of Justice Catastor
1 Black Rose Dragon/Red Dragon Archfiend
1 Shooting Star Dragon/Red Nova Dragon
1 Mist Wurm/Gungnir, Dragon of the Ice Barrier
Side Deck: 15
2 D.D. Crow
2 Mobius the Frost Monarch
1 Dark Dust Spirit
2 Cyber Dragon
1 Effect Veiler
1 Lightning Vortex
1 Torrential Tribute
1 Mirror Force
3 Malevolent Catastrophe
1 Chimeratech Fortress Dragon
First I’ll explain the three most common ways the deck wins.
Brionac/Gishilnodon/Coelacanth OTK:
* First summon Coelacanth and discard a card to activate its effect. Special Summon 2 Oyster Meister and 2 Fishborg Blaster from your deck.
* Tune Oyster Meister and Fishborg Blaster to make Armory Arm. Oyster Meister gives you a token. Your field is Coelacanth, Armory Arm, Oyster Meister, Fishborg, and a token.
* Tune Fishborg and the token to make Formula Synchron and draw a card.
* Tune the other Oyster Meister and Formula Synchron to make Gishilnodon. Get another token. Your field is now Coelacanth, Armory Arm, Gishilnodon, and a token.
* Discard a card to bring back Fishborg Blaster. Tune Fishborg and the Token to make another Formula Synchron. Draw a card.
* Tune Formula Synchron and Armory Arm to make Brionac.
* Your field is now Brionac, Gishilnodon (at 3000), and Coelacanth. You have Brionac to bounce thier cards and that’s 8100 damage.
You do this combo when they have set monsters.
Armory Arm Colossal OTK:
* First summon Coelacanth and activate its effect by discarding a card. Special Summon 2 Oyster Meister and 2 Fishborg Blaster from your deck.
* Tune Fishborg and Coelacanth into Colossal Fighter.
* Tune the other Fishborg and Oyster Meister into Armory Arm.
* Discard a card and bring back Fishborg Blaster.
* Tune Fishborg and the second Oyster Meister into a second Armory Arm.
* Equip both Armory Arms to an opponent’s monster with over 800 attack.
* Attack with Colossal into their monster. You take a small amount of damage and they take 5600 from Armory Arm burn. Then revive Colossal and do it a second time for game.
You do this combo when you have Trunade as opposed to Cold Wave and they have a monster over 800 attack. This allows you to play around Gorz. Remember, you can’t equip Armory Arm if you play Cold Wave.
Red Nova Dragon OTK:
* Summon Coelacanth and use its effect to special summon 2 Oyster Meister and 2 Fishborg Blaster.
* Tune Fishborg and Coelacanth into Red Dragon Archfiend. Then Tune Oyster Meister and the other Fishborg Blaster to make Armory Arm. Get a token. Then revive Fishborg by discarding a card and tune with the other Oyster Meister to make a second Armory Arm. Get a second token. Your field is now Red Dragon Archfiend, Armory Arm, Armory Arm, and 2 Tokens.
* Equip Armory Arm to the other Armory Arm so that he is at 2800.
* Discard a card and revive Fishborg. Tune the Fishborg and a token to make Formula Synchron. Draw a card. Do this entire step a second time. Your field is now Red Dragon Archfiend, 2 Formula Synchrons, and Armory Arm equipped with Armory Arm.
* Tune the Red Dragon Archfiend and the 2 Formula Synchrons into Red Nova Dragon. Red Nova Dragon will be at 5500 attack.
* Attack directly with Red Nova. If they drop Gorz, attack over it with the Armory Arm and the burn damage they take will be enough for game. If they don’t drop Gorz, attack with the Armory Arm for game.
This OTK is good for playing around Gorz, however the problem with it is that they have to have no cards on the field in order for this to work. Personally, I don’t think it’s worth the space in the extra deck. If Fish become more popular, this will definitely be worth the room as open fields are common and the mirror match is tricky (whoever draws better)
How to play the deck and Common Plays:
The deck revolves around two cards; Coelacanth and either Giant Trunade or Cold Wave. You’re going to want to slow play the game, sitting behind 2000 defenders until you can get both pieces of the combo. You can dig for the combo pieces with Moray, Gold Sarcophagus, and Pot of Duality. Then once you have the two pieces, you’re going to need to be able to tribute for Coelacanth. The frog engine makes this very easy to achieve. Swap Frog is the key to the deck and puts Treeborn Frog and Ronintoadin into the graveyard. Both are instant tribute fodder. A common play you can perform is to bring back Treeborn, play Enemy Controller while still in your standby phase to tribute Treeborn and take control of their monster, and then revive Treeborn a second time. You now have the fodder needed for Coelacanth. This deck is very good for several reasons:
1. It can do more than just OTK. Most decks that just OTK are never very good. They are very linear and if you manage to stop the OTK, you win. Fish are not this way. They can very easily play a control game if they are not able to OTK. They can do this by gaining advantage through Light and Darkness plays or setting up locks that are almost impossible to break with Shooting Star Dragon.
2. Their searching ability. As I mentioned above, they have numerous ways to dig through the deck to search out their combo pieces. Moray of Greed, Pot of Duality, and Gold Sarcophagus all dig for the pieces. Moray serves a dual purpose. Oyster Meister is needed for every OTK, but they aren’t very good to draw. Moray helps with drawing them by putting them back in the deck for future Coelacanth plays and gives you an entirely new hand.
3. The ability to play around Effect Veiler. Coelacanth has a built in way to play around Veiler. Let’s say that you have searched the combo out. You bring back Treeborn and use Enemy Controller to take their monster. Now if you already have a Fishborg in the graveyard, you can discard a card to bring him back before summoning Coelacanth. Now tribute Treeborn and their monster for Coelacanth. If he Veiler’s now, Coelacanth can negate it by tributing the Fishborg and you can proceed to do your OTK.
4. Snowman Eater. This guy is amazing in the deck. He allows you to play around so many different obstacles that you might otherwise not have an out to. His high defense lets him wall against almost any low level monster. He is also a maindecked out to things like Banisher of the Radiance and Fossil Dyna. He becomes even more important in games two and three.
5. The side deck. Malevolent Catastrophe is simply amazing. People will side heavily for any OTK deck. Malevolent is an out to almost anything anyone can throw at you and no one ever sees it coming.
How to beat the deck:
Now that I’ve told you how to play the deck, I’ll tell you how to beat it. I feel this is especially important as the deck grows in popularity week-by-week. The main thing you’re going to want to do in order to beat the deck is play very aggressively. The deck has very minimal defenses in the main deck and it will certainly win if you try and slow play the game and give it a chance to set up. Playing aggressively also puts pressure on them to do something back. If they have the option of summoning Coelacanth, but don’t yet have Trunade or Cold Wave, they might not do it. If you apply pressure and get their life points low, they might not have any other choice but to summon him. This leaves you with access to your traps and a good chance that you will be able to stop it from there.
Another thing that you’re going to want to do is if you do have Effect Veiler, play it correctly. If they set up the Fishborg play, don’t waste it on Coelacanth. If you have set monsters, they’ll go into the Brionac/Gashilnodon/Coelacanth OTK. Use it on the Brionac. It will buy you a turn to come back. You might take some damage, but you won’t lose. If you have a monster on the field and they are going for Colossal and Armory Arm, Veiler the Armory Arm so that it can’t equip.
Lastly, if you don’t have anything, bluff. Set 3 back rows, especially game 1 where they can’t Malevolent you. The worst they can do is Trunade you. If they don’t have that, they won’t try and OTK you with 3 sets.
Hopefully you all enjoyed this week’s article on fish and learned something new about a powerful deck type that you may not have heard of before this article. Know that the deck exists and know how to play against it if you should run into one. They are quickly becoming more popular in the game and who knows, this might be a sleeper deck for the next championship.
