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 Gnostro.
5. Repeat.

This charming loop hinges on untapping Gnostro, Voice of the Crags with Pemmin's Aura while generating both mana and counters to keep the engine humming. As Gnostro's activated ability gains you life, Cleric Class steps in with its passive lifegain bonus to ensure you always net a +1/+1 counter on Crystalline Crawler. Removing that counter from Crystalline Crawler yields the blue mana needed to fund Pemmin's Aura's untap ability, leaving you with an endless cycle that pumps your creature and nets infinite life.
