Assault Suit + Gorilla Pack

Assault Suit

Gorilla Pack

How it works

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