Monk Gyatso + Martyrdom + Heliod, the Radiant Dawn // Heliod, the Warped Eclipse

Monk Gyatso

Martyrdom

Heliod, the Radiant Dawn // Heliod, the Warped Eclipse

How it works

1. Cast Martyrdom by paying 1, targeting Monk Gyatso.
2. Monk Gyatso triggers. Choose not to airbend it.
3. Resolve Martyrdom.
4. Activate Monk Gyatso by paying 0, targeting another nontoken creature you control.
5. Monk Gyatso triggers, airbending the targeted creature.
6. Monk Gyatso's ability from step 4 fizzles due to no longer having a legal target.
7. Cast the creature from exile by paying 0 due to Heliod
8. Repeat from step 4.
