How it works
Gain life.
Archangel of Thune triggers, putting a +1/+1 counter on each creature you control.
Herd Baloth triggers, creating a creature token.
When the creature token enters the battlefield, Lifecreed Duo triggers, causing you to gain 1 life.
Repeat from step 2.
This looping marvel relies on Archangel of Thune acting as the central engine, converting any initial life gain into a permanent growth spurt for your entire board by placing +1/+1 counters everywhere. That influx of counters directly awakens Herd Baloth, whose ability triggers upon receiving them to churn out a steady stream of 4/4 green Beast tokens. Meanwhile, Lifecreed Duo quietly watches the menagerie expand, rewarding each new arrival with the single drop of life needed to restart Archangel of Thune's cycle all over again.
