Smaug the Impenetrable + Clock of Omens + Thran Forge + Orcish Mechanics

Smaug the Impenetrable

Clock of Omens

Thran Forge

Orcish Mechanics

How it works

1. Cause Orcish Mechanics to become an artifact using Thran Forge.
2. Activate Orcish Mechanics by tapping it, dealing 2 damage to Smaug.
3. Smaug triggers, creating two Treasure tokens.
4. Activate Clock of Omens by tapping the Treasures, untapping Orcish Mechanics.
5. Repeat from step 2.

This clever loop transforms a dragon's hoard into a self-sustaining engine by turning your own pyromaniac goblin into an artifact. With Thran Forge granting artifact status to Orcish Mechanics, you can point its fiery blast directly at Smaug the Impenetrable, whose indestructible nature shrugs off the damage while triggering a bounty of Treasure tokens. Those very same Treasures feed Clock of Omens to constantly untap Orcish Mechanics, letting you repeat the whole fiery spectacle indefinitely.
