Nashi, Moon Sage's Scion (Extended Art) (NEO-459) - Kamigawa: Neon Dynasty: (Extended Art)

Ninjutsu {3} ({3}, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.)
Whenever Nashi 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.
