Appa, Steadfast Guardian + Ezzaroot Channeler + Aang, Airbending Master

Appa, Steadfast Guardian

Ezzaroot Channeler

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 transforms Ezzaroot Channeler into a crucial cost-reducing engine by tapping it for life, ensuring that any creature spells exiled via airbending can be recast for free. Appa, Steadfast Guardian and Aang, Airbending Master act as a self-sustaining pair that repeatedly flicker one another from exile, continuously re-entering the battlefield for zero mana. As they bounce back and forth, Appa triggers off the spells cast from exile to spawn an endless army of 1/1 white Ally tokens, while Aang tracks every departure to steadily grow your experience counters for future upkeeps.
