arcturus, warlock of dark

: creatures you control have prowess (when you cast a noncreature spell this creature gets +1/+1 until the end of turn)
+2: look at the top three cards of your library, if there is a noncreature spell among them you may cast it this turn
-9: exile the top seve card from every player's library, you may cast all cards exiled this way without paying their mana costs
