Fiery Ghoul

Creature -- Zombie
3/1
Haste
At end of turn, sacrifice Fiery Ghoul.
At the beginning of your upkeep, if Fiery Ghoul is in your graveyard, you may remove a red creature card in your graveyard other than Fiery Ghoul from the game. If you do, return Fiery Ghoul to play.
Planar Chaos has got me thinking about how different colors' abilities overlap. 3/1 Haste, sacrifice at end of turn. That's obviously a red creature in disguise.
