Fields of Flesh

Whenever a nontoken creature dies, exile it.
It's controller creates a 1/1 black Bird creature
token with flying and "This creature can't be sacrificed." and "At the beginning of this
creature's controller's end step, that player
loses 2 life."
This land knows war. Feeds upon it. Now our peace
could mean its imbalance. Is there no end to the
struggles of this world?
