Appa, Steadfast Guardian + Heartless Summoning + Aang, the Last Airbender

Appa, Steadfast Guardian

Heartless Summoning

Aang, the Last Airbender

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 clever loop relies on Heartless Summoning to slash the mana cost of your creatures down to nothing, allowing Appa, Steadfast Guardian and Aang, the Last Airbender to endlessly cycle in and out of exile. When Appa enters the battlefield, its ability airbends Aang, who can then be recast for free due to Heartless Summoning's cost reduction. Recasting Aang triggers Appa, Steadfast Guardian to produce a 1/1 white Ally creature token while simultaneously airbending Appa back into exile, setting the stage for Appa to be recast for zero mana and restart the loop. Because Aang, the Last Airbender also triggers Appa's token generation whenever you cast a spell from exile, this endless exchange spins out an infinite storm count alongside your limitless creature tokens.
