Cleric Class + Mine Worker + Crystalline Crawler + Pemmin's Aura

Cleric Class

Mine Worker

Crystalline Crawler

Pemmin's Aura

How it works

1. Activate Mine Worker by tapping it, causing you to gain at least 2 life.
2. Cleric Class triggers, putting a +1/+1 counter on Crystalline Crawler.
3. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .
4. Activate Pemmin's Aura's first ability by paying , untapping Mine Worker.
5. Repeat.

This elegant loop transforms humble assembly workers into a self-sustaining mana engine, heavily augmented by the passive blessing of Cleric Class to turn life gain into continuous growth. By tapping Mine Worker, you generate life that Cleric Class immediately amplifies, triggering Level 2 of the Class to place a +1/+1 counter back onto Crystalline Crawler. You then strip that very counter away using Crystalline Crawler's ability to produce the blue mana needed to pay for Pemmin's Aura, whose untap ability refreshes Mine Worker to repeat the cycle infinitely.
