万智牌机制

Airbend is a keyword action. To airbend a permanent or a spell, you exile it. As long as that card remains exiled, its owner may cast it by paying {2} rather than paying its mana cost. This doesn't change when that card can be cast. If you airbend a creature that an opponent owns during your turn, they'll usually have to wait until their next turn to cast it again.
