Archangel of Thune + Herd Baloth + Haliya, Guided by Light

Archangel of Thune

Herd Baloth

Haliya, Guided by Light

How it works

1. Gain life.
2. Archangel of Thune triggers, putting a +1/+1 counter on each creature you control.
3. Herd Baloth triggers, creating a creature token.
4. When the creature token enters the battlefield, Haliya triggers, causing you to gain 1 life.
5. Repeat from step 2.

This loop starts simply by triggering any initial lifegain, which allows Archangel of Thune to distribute +1/+1 counters across your entire board thanks to its passive lifegain-triggered ability. Whenever those counters land on Herd Baloth, its triggered ability responds by creating a 4/4 green Beast token. The arrival of that new token immediately causes Haliya, Guided by Light to trigger and grant you 1 life, which feeds right back into Archangel of Thune to keep the self-sustaining cycle of growth going endlessly.
