Matak, Light-Bound Deceiver

Partner with Bodan, the Cold-Hearted.
When Matak, Light-Bound Deceiver enters the battlefield, reveal the top seven cards of your library. You may put a noncreature, nonland card from among them into your hand. If you do, you lose life equal to its converted mana cost. Put the rest of the revealed cards on the bottom of your library in any order.
