Jon Irenicus, Shattered One + Covetous Dragon

Jon Irenicus, Shattered One

Covetous Dragon

How it works

1. At the beginning of your end step, Jon Irenicus triggers, giving control of Covetous Dragon to an opponent who controls no artifacts.
2. When Covetous Dragon's controller controls no artifacts, Covetous Dragon triggers, causing them to sacrifice it.
3. However, Covetous Dragon cannot be sacrificed due to its ability.
4. Covetous Dragon triggers again, creating a mandatory infinite loop that causes the game to end in a draw.

This insidious loop hinges on Jon Irenicus, Shattered One handing away Covetous Dragon at the end step, complete with a terrifying grant that explicitly states it can't be sacrificed. Because the dragon's controller happens to control no artifacts, Covetous Dragon's native upkeep-or-end-step trigger demands that it sacrifice itself, which directly contradicts the protection bestowed by Jon Irenicus, Shattered One. This creates an unyielding, mandatory interaction that instantly forces the game into a draw as the trigger endlessly repeats its futile attempt to sacrifice the creature.
