Appa, Steadfast Guardian + Hamza, Guardian of Arashin + Aang, Airbending Master

Appa, Steadfast Guardian

Hamza, Guardian of Arashin

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 brilliant loop achieves infinity by leveraging Appa, Steadfast Guardian and Aang, Airbending Master to continuously exile and recast one another for free, while Hamza, Guardian of Arashin lurks as the vital engine making those casts cost zero. Because Aang's airbending causes permanents to leave the battlefield without dying, his ability steadily accrues experience counters to reward your patience, though the loop itself generates infinite creature tokens directly off Appa's trigger. As a delightful bonus, Hamza's cost-reduction static ability also relies on creatures with +1/+1 counters to make sure this airborne cycle can spin endlessly without draining your mana.
