Treebeard, Gracious Host + Scurry Oak + Anointer Priest

Treebeard, Gracious Host

Scurry Oak

Anointer Priest

How it works

1. Gain life.
2. Treebeard's second ability triggers, putting that many +1/+1 counters on Scurry Oak.
3. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
4. When the Squirrel enters the battlefield, Anointer Priest triggers, causing you to gain life.
5. Repeat from step 2.

This delightful loop transforms a simple spark of life into an unstoppable engine of growth. It all begins when you gain life, prompting Treebeard, Gracious Host to place +1/+1 counters on Scurry Oak because the Oak qualifies as a Treefolk. Those incoming counters cause Scurry Oak to trigger and birth a 1/1 Squirrel creature token, which in turn wakes up Anointer Priest to grant you 1 life upon entering the battlefield. That newly gained life feeds right back into Treebeard, Gracious Host to restart the cycle, letting you infinitely scale Scurry Oak with +1/+1 counters while generating an endless swarm of tokens and lifegain.
