When Hama enters, target opponent mills three cards. Exile up to one noncreature, nonland card from that player s graveyard. For as long as you control Hama, you may cast the exiled card during your turn by waterbending X rather than paying its mana cost, where X is its mana value. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for 1.)
