Renetus, God of Ice

If Renetus, God of Ice would leave the battlefield, instead return it to your hand.
"Renetus. It has been a long time since I heard that
name. If what you say is true, then this plane is at
risk. It is foretold that when he awakes, he will cover
our world with ice for one million years. Could you
pass the blood, please?"
