This elegant loop turns a single instance of life gain into a self-sustaining cascade of growth and token creation. Once you trigger the initial life gain, Archangel of Thune distributes a +1/+1 counter across your entire board. That counter placement immediately awakens Scurry Oak's ability, prompting it to spit out a brand new Squirrel token. The moment that token enters the battlefield, Suture Priest rewards you with a life gain trigger, which feeds right back into Archangel of Thune to restart the entire engine with a progressively stronger army.
