Cleric Class + Essence Warden + Scurry Oak

Cleric Class

Essence Warden

Scurry Oak

How it works

1. Gain life.
2. Cleric Class 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, Essence Warden triggers, causing you to gain 2 life.
5. Repeat from step 2.

This delightful loop begins the moment you trigger a life gain event, which Cleric Class supercharges with its passive replacement effect to hand out extra life. That initial jolt triggers Cleric Class's level 2 ability to place a +1/+1 counter on Scurry Oak, whose own triggered ability responds by spawning a 1/1 green Squirrel token. The new arrival immediately rouses Essence Warden, whose entry triggers a fresh wave of life gain that feeds right back into Cleric Class to keep the squirrel-and-counter factory running forever.
