Assault Suit + Barbarian Outcast

Assault Suit

Barbarian Outcast

How it works

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

This clever loop weaponizes the safety net of Assault Suit against the strict self-preservation of Barbarian Outcast. Because Barbarian Outcast demands to be sacrificed the moment its controller has no Swamps, it triggers its own demise, but the Iron Suit firmly forbids any sacrifices from occurring. When the game attempts to resolve the triggered sacrifice ability, the prevention effect causes it to immediately trigger all over again, creating an inescapable mandatory loop that halts the game entirely in a draw.
