Animate Dead

Enchant creature card in a graveyard

When Animate Dead enters, if it’s on the battlefield, it loses “enchant creature card in a graveyard” and gains “enchant creature put onto the battlefield with Animate Dead.” Return enchanted creature card to the battlefield under your control
and attach Animate Dead to it. When Animate
Dead leaves the battlefield, that creature’s controller sacrifices it.
Enchanted creature gets -1/-0.
