This elegant synergy feeds on itself by converting life gain and creature arrivals into an unstoppable growth engine. It all begins when you gain life, which immediately triggers Archangel of Thune to distribute a +1/+1 counter across your entire board. That sudden influx of counters awakens Herd Baloth, spawning a 4/4 green Beast token that triggers the chapter II/III ability of Thunder of Unity to drain your opponents while feeding you another life gain event. That fresh batch of life instantly loops Archangel of Thune back into action, perpetuating an infinite cycle of token creation, counter growth, and life manipulation.
