This elegant loop turns a single instance of life gain into an unstoppable cascade of growth. The engine is fueled by Soul Warden, which listens for the arrival of new creatures and rewards every entry with a life gain trigger. That life gain instantly wakes up Archangel of Thune, whose static-like triggered ability pumps a +1/+1 counter onto every creature you control. Those counters feed directly into Scurry Oak, which spits out a fresh Squirrel token whenever it receives a counter—bringing us right back to Soul Warden to start the cycle anew.
