Monk Gyatso + Soltari Guerrillas + Ezzaroot Channeler

Monk Gyatso

Soltari Guerrillas

Ezzaroot Channeler

How it works

1. Activate Soltari Guerrillas by paying 0, targeting itself.
2. Monk Gyatso triggers, airbending Soltari Guerrillas.
3. The Soltari Guerrillas ability fizzles due to no longer having a legal target.
4. Cast Soltari Guerrillas from exile by paying 0 due to Ezzaroot Channeler.
5. Repeat.
