Jon Irenicus, Shattered One | Phylactery Lich

Cards

At the beginning of your end step,
Jon Irenicus triggers, giving control of
Phylactery Lich to an opponent who controls no permanents with a phylactery counter on them.
When
Phylactery Lich's controller controls no permanents with a phylactery counter on them,
Phylactery Lich triggers, causing them to sacrifice it.
However,
Phylactery Lich cannot be sacrificed due to its ability.
Phylactery Lich triggers again, creating a mandatory infinite loop that causes the game to end in a draw.
