Deer Spirit Shaman

Whenever a non-human creature you control
dies, you may pay {3}. If you do, blur the top
card of your library. (Put it onto the battlefield face
down as a 2/2 creature. Turn it face up any time for
its mana cost. Non-creature and Non-planeswalker
cards cost X less to cast when turned face up.
Creatures get X +1/+1 counters when turned
face up. Planeswalkers get X loyalty counters when
turned face up. X is the number of +1/+1 counters
on it when it was a face down creature.)
