Crystalline Crawler + Necklace of Girion + Cloudstone Curio

Crystalline Crawler

Necklace of Girion

Cloudstone Curio

How it works

1. Cast the creature that's castable for in your hand by paying its mana cost
2. Necklace of Girion triggers, putting a +1/+1 counter on Crystalline Crawler.
3. Resolve the creature spell. When the creature enters, Cloudstone Curio triggers, returning the other creature that's castable for from the battlefield to your hand.
4. Activate Crystalline Crawler by removing a +1/+1 counter from it, adding .
5. Repeat.

This delightful loop creates an endless cycle of creature entrances and storm count by leveraging the unique interplay between Cloudstone Curio and your green creatures. As you cast your cheap green threat, Necklace of Girion rewards the action by steadily reinforcing Crystalline Crawler with a +1/+1 counter. Crystalline Crawler then sacrifices that very counter for mana to help fund the next iteration, while Cloudstone Curio ensures your hand stays continually restocked by bouncing your previously played creature back to safety.
