Ire Shaman

Ire Shaman can't be blocked except by two or
more creatures.
Megamorph {r} (You may cast this card face down
as a 2/2 creature for {3}. Turn it face up at any time
for its megamorph cost and put a +1/+1 counter on it.)
When Ire Shaman is turned face up, exile the top
card of your library. Until end of turn, you may
play that card.
