General Strategy:

This deck aims to summon Superancient Deepsea King Coelacanth and use its effect to Special Summon Level 4 Fish Normal monsters. This allows you to go into multiple Rank 4 plays without being hampered by the summon limit. If your Coelacanth gets stopped, you have another boss in the form of Mega Fortress Whale and Rank 4 plays without Coelacanth to keep you going.


To summon Coelacanth, this deck plays cards which send it from the Deck to the Graveyard, such as Peaceful Burial and Foolish Burial, and cards to summon it back from the Graveyard, such as Super Team Buddy Force Unite! and Monster Reborn. 


The deck also uses cards such as Buzzsaw Shark and Rescue Rabbit to summon Lavalval Chain, which sends Ice Barrier, which sends Coelacanth and recovers a starter or extender. Number 60: Dugares the Timeless can then be used to summon back the Coelacanth. In the late game cards such as Lifeless Leaffish which can be summoned off of the effect of Coelacanth and Daigusto Emeral can be used to recycle Fish monsters so Coelacanth's effect can be used again.

​

Opening Plays:


The first turn will usually be a summon of Lavalval Chain to send Ice Barrier before overlaying into Drill Driver Vespenato and setting backrow. Then, you can banish the Ice Barrier in the opponent’s turn to send Coelacanth and recur the detached material from the Lavalval Chain. 


After that, there will usually be a way to summon back Coelacanth, whether by using Super Team Buddy Force Unite! on a monster revived with Drill Driver Vespenato or Dugares the Timeless. 


You can then use Coelacanth's effect to summon all of your copies of Space Mambo, as it is the weakest Fish, and a copy of 7 Colored Fish. You can also go for Lifeless Leaffish if you want to recur and draw instead of making 2 effect Rank 4s.


For Rank 4 plays, the best one is Tornado Dragon to clear the backrow before committing to a Gem-Knight Pearl for beatdown or another play such as Abyss Dweller if you haven’t used a summon on Coelacanth.


Strengths:

​

Can consistently set up Coelacanth

 

Coelacanth is powerful

 

Backup plays such as playing normal Rank 4 Shark and Infernalqueen Salmon if you can’t bring out Coelacanth

 

The Extra Deck is very versatile

​

Weaknesses:

​

Coelacanth dies to any disruption


Has to make Lavalval Chain on first turn instead of a disruption Xyz


Drawing the Normal Fish bricks or too many revival/send cards is common

​

Can't snowball advantage without Whitefish Salvage

​

​

Closing Thoughts:

​

Fish is a great deck for people who enjoy summoning a lot of monsters and Rank 4 spamming. This should be a playable list at the very least, and a rogue tier deck in Trinity at best, just like normal Shark. If the Fish type or Sharks ever get more support, such as a generic search spell or a way to recur resources, it could even be meta in Trinity.
