Emiel the Blessed + Burning-Tree Emissary + Panharmonicon

Emiel the Blessed

Burning-Tree Emissary

Panharmonicon

How it works

1. Activate Emiel the Blessed by paying 3, blinking Burning-Tree Emissary.
2. When Burning-Tree Emissary enters the battlefield, it triggers twice, adding .
3. Repeat.

This loop turns Emiel the Blessed into a mana-positive engine by leveraging the red and green mana generated whenever Burning-Tree Emissary enters the battlefield. Ordinarily, blinking Burning-Tree Emissary would barely break even on the activation cost, but Panharmonicon steps in to double its entry trigger, yielding four mana total for every three spent. This extra mana fuels the ongoing cycle while building an infinitely repeating sequence of creature entries and exits.
