Archangel of Thune + Crystalline Crawler + Pemmin's Aura + Overgrown Arch

Archangel of Thune

Crystalline Crawler

Pemmin's Aura

Overgrown Arch

How it works

1. Activate Overgrown Arch by tapping it, causing you to gain life.
2. Archangel of Thune triggers, putting a +1/+1 counter on each creature you control.
3. Activate Crystalline Crawler ability by removing a +1/+1 counter from it, adding .
4. Activate Pemmin's Aura's ability by paying , untapping Overgrown Arch.
5. Repeat.

This intricate loop turns the humble healing of Overgrown Arch into an endless engine of growth, sustained by the divine presence of Archangel of Thune to reward every single increment of life gained with a +1/+1 counter across your entire board. That newly generated counter can then be converted into mana using Crystalline Crawler's ability, providing the exact blue energy needed to pay for Pemmin's Aura and continuously untap your defender. Because the arch's tap ability feeds the angel, and the angel's counters feed the crawler, the whole system perpetually refunds itself while pumping your creatures to infinitely massive proportions.
