Appa, Loyal Sky Bison

Lands exiled this way cannot be played from exile. (Lands that were animated by earthbend will be returned to the battlefield tapped when they're exiled.)

Tokens exiled this way will cease to exist and cannot be cast.

To airbend one or more permanents and/or spells means to exile each of those objects. For each card exiled this way, for as long as it's exiled, its owner may cast it from exile by paying {2} rather than paying its mana cost.
