Nashi Moon Sages Scion

“Ninjutsu 3B <em>(3B, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.)</em> <br> Whenever Nashi, Moon Sage's Scion deals combat damage to a player, exile the top card of each players 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.”
