Assault Suit + Slipstream Serpent

Assault Suit

Slipstream Serpent

How it works

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