Aang, Airbending Master + Aang, the Last Airbender + Ballad of the Black Flag

Aang, Airbending Master

Aang, the Last Airbender

Ballad of the Black Flag

How it works

1. Cast Aang, Airbending Master by paying 2
2. When Aang, Airbending Master enters, it triggers, airbending Aang, the Last Airbender
3. Cast Aang, the Last Airbender from exile by paying 0.
4. When Aang, the Last Airbender enters, it triggers, airbending Aang, Airbending Master.
5. Cast Aang, Airbending Master from exile by paying 0.
6. Repeat from step 2.

This clever loop hinges on the cost-reduction power of Ballad of the Black Flag's final chapter, which drops the cast cost of historic spells by {2}. Because both Aang, Airbending Master and Aang, the Last Airbender are legendary and thus historic, they each qualify for this discount, allowing them to be recast from exile for the exact {2} that their airbend abilities make available. As they continually enter and leave the battlefield to exile one another, you generate an endless cascade of enters-the-battlefield and leaves-the-battlefield triggers along with an infinite storm count.
