Archangel of Thune + Crystalline Crawler + Resplendent Mentor + Pemmin's Aura

Archangel of Thune

Crystalline Crawler

Resplendent Mentor

Pemmin's Aura

How it works

1. Activate Resplendent Mentor 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 Resplendent Mentor.
5. Repeat.

This clever loop turns a simple act of devotion into a cascade of endless growth by bridging life, mana, and counters into a closed circuit. Resplendent Mentor provides the vital spark by granting your white creatures a tap ability to gain life, which immediately triggers Archangel of Thune to distribute +1/+1 counters across your entire board. Those fresh counters feed directly into Crystalline Crawler, letting you strip one away for mana to fuel Pemmin's Aura as it repeatedly untaps the Mentor. The Aura itself holds the whole machine together, translating blue mana into the untap steps needed to keep the cycle spinning while leaving any leftover counters to permanently dwarf your army.
