Treebeard, Gracious Host + Scurry Oak + Prosperous Innkeeper

Treebeard, Gracious Host

Scurry Oak

Prosperous Innkeeper

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, Prosperous Innkeeper triggers, causing you to gain life.
5. Repeat from step 2.

This elegant loop starts with a spark of life that sets Treebeard, Gracious Host into motion, using its triggered ability to place +1/+1 counters on Scurry Oak. That influx of counters makes Scurry Oak's secondary trigger fire off, spawning a fresh 1/1 Squirrel token. As that token enters the battlefield, Prosperous Innkeeper gently catches the moment, padding your life total and feeding right back into Treebeard, Gracious Host to keep the cycle spinning infinitely.
