This clever loop spins into motion the moment you trigger any life gain, using Cleric Class to turn that single bump into a +1/+1 counter on Scurry Oak. That counter causes Scurry Oak to spawn a Squirrel token, which in turn makes Distinguished Conjurer trigger and hand you life. Because Cleric Class's replacement effect increases your life gained, and Distinguished Conjurer's entry brings another creature into the fold, the cycle feeds endlessly into itself—pumping Scurry Oak with infinite +1/+1 counters while flooding your board with an infinite army of tokens.
