Appa, Steadfast Guardian + Animar, Soul of Elements + Aang, Airbending Master

Appa, Steadfast Guardian

Animar, Soul of Elements

Aang, Airbending Master

How it works

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

This brilliant loop relies on Animar, Soul of Elements to continually discount creature spells down to zero mana as its +1/+1 counters pile up. With that cost reduction in place, you flash in Appa, Steadfast Guardian, whose entry airbends Aang, Airbending Master into exile. You can then recast Aang for free, triggering Appa to create a 1/1 Ally token while Aang's entry airbends Appa right back out. Repeating this infinite dance of blink and recast triggers your +1/+1 counters, token generation, leaves-the-battlefield counts, and storm count all at once.
