Derevi, Empyrial Tactician + Emiel the Blessed + Karametra's Acolyte

Derevi, Empyrial Tactician

Emiel the Blessed

Karametra's Acolyte

How it works

1. Activate Karametra's Acolyte by tapping it, adding at least .
2. Activate Emiel by paying 3, blinking Derevi.
3. When Derevi enters the battlefield, it triggers, untapping Karametra's Acolyte.
4. Repeat.

This glittering loop centers around Karametra's Acolyte, whose devotion-fueled green mana production must comfortably exceed the three mana required to activate Emiel the Blessed. By sinking that floating mana into Emiel's ability, you repeatedly exile and return Derevi, Empyrial Tactician to the battlefield. Every time Derevi enters, its triggered ability untaps Karametra's Acolyte, refunding your mana investment and leaving you with an ever-expanding surplus of green mana along with infinite enters-the-battlefield and leaves-the-battlefield triggers.
