Smaug the Impenetrable + Metalwork Colossus + Blasting Station + Exalted Sunborn

Smaug the Impenetrable

Metalwork Colossus

Blasting Station

Exalted Sunborn

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 Exalted Sunborn.
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 intricate loop turns a miniature dragon into an endless foundry of wealth and ammunition, anchored by the recursion of Metalwork Colossus. By utilizing Blasting Station to deal noncombat damage to Smaug the Impenetrable, you trigger its wrath, which Exalted Sunborn doubles into a tidal wave of Treasure tokens. Those very tokens provide the fuel to sacrifice back to Metalwork Colossus to pull it straight from the graveyard, allowing you to replay the Colossus for free and continuously untap the Blasting Station to repeat the massacre.
