Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
Relentless (Whenever this creature becomes blocked
by one or more creatures, you may look at the top X cards of our library, where X is the number of creatures blocking this creature. Put an instant card among them into your hand and the rest on the bottom of your library in any order.)
