Emiel the Blessed + Burning-Tree Emissary + Yarok, the Desecrated

Emiel the Blessed

Burning-Tree Emissary

Yarok, the Desecrated

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 brilliant loop centers on Emiel the Blessed, whose activated ability normally costs more mana than it generates to blink a creature. However, when you target Burning-Tree Emissary, its entry ability produces a net-positive surge of red and green mana. Yarok, the Desecrated is the engine's true catalyst, doubling every entry trigger to ensure that Burning-Tree Emissary yields {R}{R}{G}{G} each cycle instead of just {R}{G}. With Yarok's duplication fueling the loop, the mana generated easily covers Emiel the Blessed's blink cost while leaving an infinite surplus of red and green mana behind.
