Ikit Claw

Ninjitsu {3}{B} ({3}{B}, Return an unblocked attacker you control to your hand: Put this card onto the battlefield from your hand tapped and attacking.) Whenever Ikit Claw, Master Engineer deals combat damage to a player, exile the top card of each player’s library. Until the end of turn, you may play one of those cards. If you cast a spell this way, pay life equal to it’s mana value rather than paying it’s mana cost. {/color#ffffff}
