Monk Gyatso + Shuko + Sage of the Beyond

Monk Gyatso

Shuko

Sage of the Beyond

How it works

1. Activate Shuko's equip ability by paying 0, targeting another nontoken creature you control.
2. Monk Gyatso triggers, airbending the targeted creature.
3. The Shuko ability fizzles due to no longer having a legal target.
4. Cast the creature from exile by paying 0 due to Sage of the Beyond.
5. Repeat.
