Derevi, Empyrial Tactician + Emiel the Blessed + Mona Lisa, Science Geek

Derevi, Empyrial Tactician

Emiel the Blessed

Mona Lisa, Science Geek

How it works

1. Activate Mona Lisa 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 Mona Lisa.
4. Repeat.

This infinite loop turns Mona Lisa, Science Geek into a powerhouse mana producer by using her own generated mana to fund Emiel the Blessed's blink ability. Each time Emiel banishes and returns Derevi, Empyrial Tactician to the battlefield, Derevi's entrance trigger untaps Mona Lisa so she can tap for mana again. The beauty of this engine lies in Emiel's ability to seamlessly reset the loop, letting you continuously tap and untap your mana source to generate infinite colored mana and infinite creature enters-the-battlefield triggers.
