Monk Gyatso + Lightning Greaves + Karametra's Acolyte

Monk Gyatso

Lightning Greaves

Karametra's Acolyte

How it works

1. Activate Lightning Greaves' equip ability by paying 0, targeting Karametra's Acolyte.
2. Monk Gyatso triggers. Choose not to airbend Karametra's Acolyte.
3. Resolve Lightning Greaves' ability, attaching it to Karametra's Acolyte.
4. Activate Karametra's Acolyte by tapping it, adding at least .
5. Activate Lightning Greaves' equip ability by paying 0, attaching it to Monk Gyatso.
6. Activate Lightning Greaves' equip ability by paying 0, targeting Karametra's Acolyte.
7. Monk Gyatso triggers, airbending Karametra's Acolyte.
8. The Lightning Greaves ability fizzles due to no longer having a legal target.
9. Cast Karametra's Acolyte from exile by paying 2.
10. Repeat.

This clever loop relies on Monk Gyatso turning the targeting process of Lightning Greaves into a repeatable removal engine for your own permanents. By repeatedly retargeting Lightning Greaves back and forth between Monk Gyatso and Karametra's Acolyte, Monk Gyatso’s trigger continuously exiles and re-enters Karametra's Acolyte for just {2}. Because Karametra's Acolyte enters the battlefield fresh each time, you can tap it anew to generate a massive surplus of green mana, easily covering the {2} recast cost while netting infinite mana, storm, and enters-the-battlefield triggers.
