Heliod, Sun-Crowned + Impassioned Orator + Scurry Oak

Heliod, Sun-Crowned

Impassioned Orator

Scurry Oak

How it works

1. Gain life.
2. Heliod triggers, putting a +1/+1 counter on Scurry Oak.
3. Scurry Oak triggers, creating a creature token.
4. When the creature token enters the battlefield, Impassioned Orator triggers, causing you to gain 1 life.
5. Repeat from step 2.

This loop is fueled by a single spark of life, which Heliod, Sun-Crowned uses to place a +1/+1 counter on Scurry Oak. That influx of power triggers Scurry Oak to spawn a 1/1 green Squirrel creature token, which in turn causes Impassioned Orator to trigger upon entering the battlefield and grant you another increment of life. This new lifegain feeds right back into Heliod, Sun-Crowned to restart the cycle, compounding infinitely to grow Scurry Oak into a colossal threat while flooding your board with endless tokens.
