Allure of Immortality

Enchant creature you control
When enchanted creature dies, if it didn't have
any -1/-1 counters on it, exile Allure of Immortality, then return the creature to the battlefield under your control with a -1/-1
counter on it. If you do, it becomes a Zombie in addition to its other types, then return Allure of Immortality to the battlefield attached to that creature.
{3}{b}: Remove a -1/-1 counter from enchanted
creature.
