Derevi, Empyrial Tactician + Emiel the Blessed + Rofellos, Llanowar Emissary

Derevi, Empyrial Tactician

Emiel the Blessed

Rofellos, Llanowar Emissary

How it works

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

This clever green-white-blue engine uses Emiel the Blessed as a repeatable blink outlet that continually resets Derevi, Empyrial Tactician, whose enters-the-battlefield trigger untaps Rofellos, Llanowar Emissary. Because Rofellos produces enough green mana from your Forests to more than cover Emiel's activation cost, the loop is completely self-sustaining. The result is an endless cascade of leaves-the-battlefield and enters-the-battlefield triggers that floods your mana pool with infinite green mana.
