Eternal Scourge + Young Deathclaws + Crystalline Crawler + Goblin Bombardment + Vorinclex, Monstrous Raider

Eternal Scourge

Young Deathclaws

Crystalline Crawler

Goblin Bombardment

Vorinclex, Monstrous Raider

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 Vorinclex.
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 Goblin Bombardment by sacrificing Eternal Scourge.
5. Repeat.

This clever loop turns the graveyard into a self-sustaining engine by leveraging Young Deathclaws to grant Eternal Scourge its scavenge ability. Because Eternal Scourge can be cast directly from exile, every time you exile it to scavenge, you set up your next iteration. Crystalline Crawler acts as your mana battery, turning the resulting counters into the exact resources you need, while Vorinclex, Monstrous Raider doubles those counters to generate a net surplus of mana with every cycle. Finally, Goblin Bombardment converts your looping creature into an infinite stream of damage and death triggers to close out the game.
