This clever loop sets in motion a self-sustaining cycle where every single piece feeds the other, turning a single instance of life gain into an endless cascade. Case of the Uneaten Feast acts as the life-gaining engine, turning every creature entry into life that is immediately amplified by Cleric Class's replacement effect. That boosted life gain triggers Cleric Class's level 2 ability to place a +1/+1 counter on Scurry Oak, which in turn fires off its own triggered ability to spawn a fresh Squirrel token—feeding right back into Case of the Uneaten Feast to restart the loop and yield infinite tokens and counters.
