Appa, Steadfast Guardian + Sami, Wildcat Captain + Aang, Airbending Master

Appa, Steadfast Guardian

Sami, Wildcat Captain

Aang, Airbending Master

How it works

1. Cast Appa by paying .
2. When Appa enters, it triggers, airbending Aang.
3. Cast Aang from exile by paying 0.
4. Appa triggers, creating a 1/1 Ally creature token.
5. When Aang enters, it triggers, airbending Appa.
6. Cast Appa from exile by paying 0.
7. Repeat from step 2.

This elegant loop relies on Sami, Wildcat Captain to provide massive affinity for artifacts that reduces the recasting cost of both Appa, Steadfast Guardian and Aang, Airbending Master down to zero. Once you cast Appa to airbend Aang into exile, you can immediately recast Aang for free, triggering Appa to create a 1/1 white Ally creature token. That entry then causes Aang to airbend Appa right back out, letting you loop the process indefinitely while generating an endless supply of triggers, tokens, and experience counters.
