This loop transforms a humble spark of healing into an unstoppable engine of growth by closing a recursive loop between life gain and creature creation. It all starts when Lunarch Veteran triggers to grant you life upon a creature's arrival, amplified by Cleric Class's first-level static replacement effect to boost your life gain and simultaneously trigger its second-level ability whenever you gain life. That life gain places a +1/+1 counter on Scurry Oak, whose own static-triggered ability reacts to those counters by spawning a Squirrel token. When that token enters the battlefield, it brings back Lunarch Veteran's entry trigger to restart the entire sequence, letting you build an arbitrarily large army and infinitely massive creatures in one unbroken chain.
