Hazaar Voidwatcher

Flying, vigilance, ward {3}
Whenever you cast a spell, if you didn't cast it
from your hand, put a +1/+1 counter on Hazaar.
{w/u}{w/u}: Exile a card at random from your
graveyard. If it's a nonland card, you may
cast that card this turn. Activate only once
each turn and only any time you could cast
a sorcery.
