Jon Irenicus, Shattered One + Skeleton Ship

Jon Irenicus, Shattered One

Skeleton Ship

How it works

1. At the beginning of your end step, Jon Irenicus triggers, causing an opponent who controls no Islands to gain control of Skeleton Ship.
2. Skeleton Ship triggers, causing the opponent to sacrifice it.
3. However, Skeleton Ship cannot be sacrificed due to its ability granted by Jon Irenicus.
4. Skeleton Ship triggers again, creating a mandatory infinite loop that causes the game to end in a draw.
