Archangel of Thune + Scurry Oak + Haliya, Guided by Light

Archangel of Thune

Scurry Oak

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. Scurry Oak 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 sets in motion an escalating cycle of growth by turning every instance of life gain into a cascading board presence. Whenever you trigger lifegain, Archangel of Thune distributes +1/+1 counters across your entire board, which immediately makes Scurry Oak trigger to spawn a Squirrel token. That entering token causes Haliya, Guided by Light to trigger and grant you 1 life, which feeds right back into Archangel of Thune to keep the loop going indefinitely while bloating your creatures to colossal proportions.
