Assault Suit + Ronom Serpent

Assault Suit

Ronom Serpent

How it works

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