Eternal Scourge + Young Deathclaws + Crystalline Crawler + Thermopod + Branching Evolution

Eternal Scourge

Young Deathclaws

Crystalline Crawler

Thermopod

Branching Evolution

How it works

1. Activate Eternal Scourge's scavenge ability, granted to it by Young Deathclaws, by paying 3 and exiling Eternal Scourge from your graveyard, putting six +1/+1 counters on Crystalline Crawler due to Branching Evolution.
2. Activate Crystalline Crawler six times by removing six +1/+1 counters from it, adding 6.
3. Cast Eternal Scourge from exile by paying 3.
4. Activate Thermopod by sacrificing Eternal Scourge.
5. Repeat.

This fascinating loop turns a creature's recursive nature into an engine of boundless energy, anchored by Young Deathclaws granting every card in your graveyard the scavenge ability—including Eternal Scourge itself. When you exile Eternal Scourge to scavenge, Branching Evolution doubles the incoming counters, placing a massive surplus onto Crystalline Crawler. You can then crack those counters for mana and sacrifice the recastable Eternal Scourge to Thermopod to fund the next iteration, generating infinite red mana, death triggers, and storm count along the way.
