Necromancy

You may choose to play Necromancy as an
instant; if you do bury it at end of turn.
When you play Necromancy, choose target
creature card in any graveyard. When
Necromancy comes into play, put that creature
into play as though it were just played and
Necromancy becomes a creature enchantment
that targets the creature. If Necromancy leaves
play, bury the creature.
