Cleric Class + Ajani's Welcome + Scurry Oak

Cleric Class

Ajani's Welcome

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, Ajani's Welcome triggers, causing you to gain 2 life.
5. Repeat from step 2.

This clever loop transforms a single instance of lifegain into a self-sustaining engine by bridging creature generation and stat growth. Once you kick things off, Cleric Class's replacement effect bumps up your life totals while simultaneously fueling Scurry Oak with +1/+1 counters. Every time those counters land on Scurry Oak, it spits out a Squirrel token, which immediately triggers Ajani's Welcome to feed more life back into the Cleric Class.
