Savathûn, the Witch Queen

Flying, morph {1}{u}{b}
Lightbearer
When Savathun enters the battlefield or is turned
face up, you may look at the top 3 cards of your
deck and seperate them into a face-up pile and a
face-down pile. Target opponent chooses a pile to
put into your hand. The other is put into your
graveyard.
{2}: You may illuminate Savathun. If you don't,
turn it face down.
