How it works
Gain life.
Light of Promise triggers, putting a +1/+1 counter on Scurry Oak.
Scurry Oak triggers, creating a creature token.
When the creature token enters the battlefield, Impassioned Orator triggers, causing you to gain 1 life.
Repeat from step 2.
This charming loop spins completely out of control once you kick-start the life-total engine with Impassioned Orator on the battlefield. Every time you gain life, Light of Promise commands Scurry Oak to grow larger by placing a +1/+1 counter on it. That sudden influx of counters immediately satisfies Scurry Oak's secondary condition, spawning a fresh Squirrel token that triggers Impassioned Orator all over again to restart the entire sequence.
