This combo use "First Penguin" as a Starter and "Deepsea King Coelacanth" a Key Card for this combo to set up Ghoti for next turn along side generic WATER boss monsters: Dragite, Gymir, and recently release Link-3 Medius. Require 2 discard in total.

Coelacanth part of the combo require attention to zone as its effect will fill every MMZ. as general rule always summon in a way that it would free zone under EMZ when you summon Anemone

Prefer quick synchro during Opponent turn:

• Askaan -> 1st Deep Beyond -> 2nd Deep Beyond
• Askaan, Deep beyond, Whale (in no order)

Note about Link monsters: Anemone and Abyss Keeper are important card for Coel strategy. Altho you can argue that you can pick either Abyss Keeper or Anemone. The link-3 monster like Medius and Neptabyss always have priority LOWER than the first 2. If you want to play the link-3, the following card are flex spot: Monoceros, Typhon, S:P Little Knight, 2nd Arionpos, and Toxic Boxfish
