Notes & Combos

After a harrowing journey from Diamond V to Master with the Coelacanth variant, I decided to cut down on the bricks, which led me to a Coel-less 45c version, which worked out well, though I still think it is not optimal.

Porpoise is an excellent Synchro 6 as it enables Dweller and Dragite, which left me some extra ED spaces as it can do the heavy lifting during the combo.

Most of the extra ED space went into going second options like White Aura Whale or Abyssgaios (though I never summoned both).

1 Small World was for unbricking purposes (and also because I kept bricking on Virtue Stream which was extremely annoying, even though it would've made my board more threatening).

If I were to continue developing this deck again, I'll definitely try out the Coral Dragon + Prima Donna version as it can perform more searches and lets me stack either Neptabyss or Dragoons in deck as follow-up or interruption.
