Archangel of Thune + Herd Baloth + Aunt May

Archangel of Thune

Herd Baloth

Aunt May

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, Aunt May triggers, causing you to gain 1 life.
5. Repeat from step 2.

This loop turns any initial instance of lifegain into a self-sustaining engine, anchored by Archangel of Thune's passive lifelink and its triggered ability to pump your board with +1/+1 counters. Every time those counters land, Herd Baloth responds by spawning a 4/4 green Beast creature token, which immediately drops onto the battlefield. That new arrival triggers Aunt May, granting you 1 life to restart Archangel of Thune's trigger all over again.
