Cruel King Sereal

Haste, First Strike
When Cruel King Sereal attacks or enters, exile
the top 4 cards of your library. If you exiled a creature card, create a 2/2 black Zombie creature token for each. If you exiled a land card, add one mana of either {r} or {b} for each. If you exiled a noncreature, nonland card, you may cast that card until the end of turn.
