Mine Worker + Heliod, Sun-Crowned + Crystalline Crawler + Freed from the Real

Mine Worker

Heliod, Sun-Crowned

Crystalline Crawler

Freed from the Real

How it works

1. Activate Mine Worker by tapping it, causing you to gain at least 1 life.
2. Heliod 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 Freed from the Real's second ability by paying , untapping Mine Worker.
5. Repeat.

This clever loop starts with Mine Worker, whose tap ability generates the life gain needed to kick off the engine. That life gain triggers Heliod, Sun-Crowned, which responds by placing a +1/+1 counter onto Crystalline Crawler. You can then immediately cash in that very counter using Crystalline Crawler's ability to produce the blue mana required to fuel Freed from the Real, whose untap ability refreshes Mine Worker to start the whole cycle over again.
