Stuck in the Cemetery 1U
Enchantment - Aura (Common)
When Stuck in the Cemetery enters the battlefield, if you have five or more cards in your graveyard, tap enchanted creature.
Enchanted creature doesn’t untap during its controller’s untap step. "Help! I'm not a zombie! Let me out!"
Bit ironic that the easiest route to use this requires self-mill, and the usual Innistrad draft self-mill strategy is Zombies.
