Appa, Steadfast Guardian

Description

Appa, Steadfast Guardian (TLA-316) is a legendary white Creature — Bison Ally from the Avatar: The Last Airbender expansion. It has Flash and Flying and an enters-the-battlefield ability that exiles any number of your other nonland permanents allowing them to be cast from exile for {2} instead of their mana costs. Whenever you cast a spell from exile using that effect, you create a 1/1 white Ally token, supporting token generation and tempo plays.
