Jon Irenicus, Shattered One + Ronom Serpent

Jon Irenicus, Shattered One

Ronom Serpent

How it works

1. At the beginning of your end step, Jon Irenicus triggers, giving 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 its ability.
4. Ronom Serpent triggers again, creating a mandatory infinite loop that causes the game to end in a draw.
