Heliod, Sun-Crowned + Crystalline Crawler + Freed from the Real + Gnostro, Voice of the Crags

Heliod, Sun-Crowned

Crystalline Crawler

Freed from the Real

Gnostro, Voice of the Crags

How it works

1. Activate Gnostro 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 Gnostro.
5. Repeat.

This clever loop relies on Gnostro, Voice of the Crags to continuously activate its life-gaining ability, which prompts Heliod, Sun-Crowned to distribute a +1/+1 counter. That fresh counter is immediately harvested by Crystalline Crawler to generate the blue mana needed for Freed from the Real to untap Gnostro, resetting the entire engine. As a result, you can cycle this sequence endlessly to trigger infinite lifegain and trigger any associated life-total payoffs.
