Appa, Loyal Sky Bison (TLA)

Legendary Creature — Bison Ally

Flying Whenever Appa enters or attacks, choose one — • Target creature you control gains flying until end of turn. • Airbend another target nonland permanent you control. (Exile it. While it's exiled, its owner may cast it for {2} rather than its mana cost.)

Reliable flying threat and utility engine for white midrange and Commander decks. Appa provides evasion while offering flexible value through its Airbend mode, which effectively cheats mana costs on your best permanents. The repeatable activation on entry and attack makes it a solid top-end play that generates advantage over multiple turns, though it requires a developed board to maximize the second mode. Best in decks with high-impact permanents that benefit from cost reduction, particularly in Commander where the tempo swing is most pronounced.
