Ikit Claw, Chief Warlock

Ninjutsu ({3}{b}, Return an unblocked attacker you control to hand: Put this card onto the battlefield from
your hand tapped and attacking.)
Whenever Ikit Claw, Chief Warlock deals combat damage to a player, exile the top card of each
player's library. Until end of turn, you may play
one of those cards. If you cast a spell this way,
pay life equal to its mana value rather than
paying its mana cost.
