Appa, Steadfast Guardian + Rakdos, Lord of Riots + Aang, the Last Airbender

Appa, Steadfast Guardian

Rakdos, Lord of Riots

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 engine leverages Rakdos, Lord of Riots to reduce creature spell costs to zero once opponents have lost life, allowing Appa, Steadfast Guardian and Aang, the Last Airbender to continuously exile and recast each other for free. Every time Appa enters, it airbends Aang so he can be recast, and similarly, Aang's entry airbends Appa right back. As you cycle these legendary figures in and out of exile, Appa's secondary trigger capitalizes on you casting spells from exile to generate an infinite army of 1/1 white Ally creature tokens, while simultaneously racking up an infinite storm count and endless enters-the-battlefield and leaves-the-battlefield triggers.
