Smaug the Impenetrable + Metalwork Colossus + Blasting Station + Worldwalker Helm

Smaug the Impenetrable

Metalwork Colossus

Blasting Station

Worldwalker Helm

How it works

1. Activate Blasting Station by tapping it and sacrificing Metalwork Colossus, dealing 1 damage to Smaug.
2. Smaug triggers, creating two artifact tokens due to Worldwalker Helm.
3. Activate Metalwork Colossus by sacrificing the 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 clever loop harnesses the indestructible toughness of Smaug the Impenetrable to convert targeted damage into a steady stream of wealth. By pinging the dragon with Blasting Station, you trigger Smaug's noncombat damage ability, which Worldwalker Helm supercharges to crank out an extra artifact token alongside your treasures. Those generated tokens are then fed directly into Metalwork Colossus's recursion ability, letting you fish the giant construct back from the graveyard for free thanks to the massive mana value discount provided by your noncreature artifacts. As Metalwork Colossus repeatedly re-enters the battlefield, Blasting Station untaps itself to keep the firing line active, creating a self-sustaining engine of infinite sacrifice and artifact creation.
