one target creature gets -X/-X until end of turn.
Rooh-Dozd's power is equal to the number of
cards exiled with it.
{b}{b}: Exile target creature card from a graveyard.
Create a token that's a copy of it, except it's a
2/2 black Zombie with decayed. (It can't block.
When it attacks, sacrifice it at end of combat.)
