Derevi, Empyrial Tactician + Emiel the Blessed + Accomplished Alchemist

Derevi, Empyrial Tactician

Emiel the Blessed

Accomplished Alchemist

How it works

1. Activate Accomplished Alchemist's second ability by tapping it, adding at least three mana of any color.
2. Activate Emiel by paying 3, blinking Derevi.
3. When Derevi enters the battlefield, it triggers, untapping Accomplished Alchemist.
4. Repeat.

This loop relies on an infinite-mana engine fueled by Accomplished Alchemist, whose second tap ability scales with life gain to generate a surplus of colored mana whenever you need it. By investing that mana into Emiel the Blessed's activation cost, you can repeatedly exile and blink Derevi, Empyrial Tactician. Every time Derevi enters the battlefield, its triggered ability untaps Accomplished Alchemist, resetting it to produce more mana than Emiel consumed.
