Monk Gyatso + Eye of Ugin + Puresteel Paladin

Monk Gyatso

Eye of Ugin

Puresteel Paladin

How it works

1. Activate an Equipment's equip ability by paying 0 due to Puresteel Paladin, targeting the Eldrazi.
2. Monk Gyatso triggers, airbending the Eldrazi.
3. The Equipment's ability fizzles due to no longer having a legal target.
4. Cast the Eldrazi from exile by paying 0 due to Eye of Ugin.
5. Repeat.
