Light of Promise + Scurry Oak + Lifecreed Duo

Light of Promise

Scurry Oak

Lifecreed Duo

How it works

1. Gain life.
2. Light of Promise 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, Lifecreed Duo triggers, causing you to gain 1 life.
5. Repeat from step 2.

This loop transforms a single instance of lifegain into a self-sustaining engine by tying together triggers that continuously feed each other. It all begins when Light of Promise pumps Scurry Oak with +1/+1 counters each time you gain life, which in turn causes Scurry Oak to spawn a Squirrel token. That token's arrival triggers Lifecreed Duo to grant you 1 life, immediately satisfying the condition to restart Light of Promise and keep the cycle spinning endlessly.
