This delightful loop turns any initial spark of life into an exponentially growing menagerie, fueled entirely by the clever synergy between your enchanted creature and your creatures entering and leaving the battlefield. Once you kick things off, Light of Promise transforms that life gain into a flurry of +1/+1 counters on Herd Baloth whenever life is gained. Because Herd Baloth triggers on those counters to create a 4/4 green Beast token, every new beast dropping onto the battlefield causes Lunarch Veteran to trigger and return the favor by granting you another life. This closed loop feeds seamlessly back into Light of Promise, letting you spin up infinite lifegain, endless +1/+1 counters, and an unbounded army of Beasts.
