This control deck aims to either rush into Lancea for Raiho/warlock interruptions or set up a Kosmoclor/curse lock on your opponent.

The First Penguin is the best new piece of support for water decks. Using it can grab you either Ran Aegerine for combo starters (graydle dragon as target) or Numen Erat Testudo, a niche floodgate which is searchable through Penguin Brave as First Penguin's target.

Impulse is definitely the best non-engine you can run in this deck, but for the sake of price as of May 2026, I am going to sub in something else IRL.
