This loop is a masterclass in turning a single instance of life gain into a self-sustaining avalanche, bridging creature synergy with artifact mechanics. Biotransference does the heavy lifting of turning your entire team—including Scurry Oak and Archangel of Thune—into artifacts, which ensures that Pactdoll Terror sees every new arrival as an artifact entering the battlefield to drain your opponents and keep your life total ticking upward. Whenever you gain that life, Archangel of Thune distributes +1/+1 counters to your creatures, which in turn triggers Scurry Oak to churn out a token while growing bigger itself. Because all these creatures are artifacts thanks to Biotransference, that new token entering the battlefield immediately trips Pactdoll Terror's life-gaining trigger once more, feeding right back into the Archangel to loop the entire process infinitely.
