Smaug the Impenetrable + Metalwork Colossus + Blasting Station + Parallel Lives

Smaug the Impenetrable

Metalwork Colossus

Blasting Station

Parallel Lives

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 Parallel Lives.
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 turns the indomitable dragon Smaug the Impenetrable into a personalized treasure vault by leveraging Blasting Station to deal noncombat damage, which is doubled into a double-handful of loot thanks to Parallel Lives. Those freshly minted treasures aren't just for show; they provide the exact sacrifice fodder needed to trigger Metalwork Colossus's graveyard-to-hand recursion. Because the Colossus costs zero mana to recast when you control enough artifacts, it drops right back onto the battlefield, neatly untapping Blasting Station along the way to repeat the entire cycle for an endless chain of sacrifices and triggers.
