This delightful feedback loop turns a simple life gain event into an overwhelming stampede. It all kicks off when Soul Warden watches your board state grow, rewarding every new arrival with a point of life. That life gain immediately supercharges Light of Promise, which translates the healing into relentless +1/+1 counters for your enchanted Herd Baloth. In turn, whenever those counters land, Herd Baloth's triggered ability rewards you with a fresh 4/4 Beast token, which immediately drops onto the battlefield to trigger Soul Warden all over again and keep the cycle spinning infinitely.
