Smaug the Impenetrable + Metalwork Colossus + Academy Manufactor + Blasting Station

Smaug the Impenetrable

Metalwork Colossus

Academy Manufactor

Blasting Station

How it works

1. Activate Blasting Station by tapping it and sacrificing Metalwork Colossus, dealing 1 damage to Smaug.
2. Smaug triggers, creating a Food, Clue and Treasure token due to Academy Manufactor.
3. Activate Metalwork Colossus by sacrificing two artifact tokens, returning Metalwork Colossus from your graveyard to your hand.
4. Cast Metalwork Colossus by paying 0.
5. When Metalwork Colossus enters, Blasting Station triggers, untapping Blasting Station
6. Repeat.

This loop transforms the indestructible dragon Smaug the Impenetrable into a massive mana and token engine by weaponizing Blasting Station's damage to trigger its wealth. Because Academy Manufactor turns every single Treasure creation into a triad of Clues, Foods, and Treasures, sacrificing those abundant tokens easily fuels Metalwork Colossus's recursion back to your hand. You can then replay the Colossus for free—its cost reduced to zero by the rich noncreature artifacts you control—which neatly untaps Blasting Station via its creature-entry trigger to restart the cycle.
