Assault Suit + Sea Serpent

Assault Suit

Sea Serpent

How it works

1. If needed, give control of Sea Serpent to an opponent who controls no Islands.
2. When Sea Serpent's controller controls no Islands, Sea Serpent triggers, causing them to sacrifice it.
3. However, Sea Serpent cannot be sacrificed due to Assault Suit.
4. Sea Serpent triggers again, creating a mandatory infinite loop that causes the game to end in a draw.
