Derevi, Empyrial Tactician + Emiel the Blessed + Harabaz Druid

Derevi, Empyrial Tactician

Emiel the Blessed

Harabaz Druid

How it works

1. Activate Harabaz Druid 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 Harabaz Druid.
4. Repeat.

This brilliant loop is built around the synergy of untapping and blinking to churn out boundless resources. By tapping Harabaz Druid for a bounty of mana, you generate the fuel needed to activate Emiel the Blessed's exile-and-return ability on Derevi, Empyrial Tactician. Every time Derevi re-enters the battlefield, its triggered ability untaps Harabaz Druid, resetting your mana source to do it all over again.
