Smaug the Impenetrable + Clock of Omens + Orcish Mechanics + Neurok Transmuter

Smaug the Impenetrable

Clock of Omens

Orcish Mechanics

Neurok Transmuter

How it works

1. Cause Orcish Mechanics to become an artifact using Neurok Transmuter.
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 contraption uses Neurok Transmuter's first ability to turn Orcish Mechanics into an artifact, allowing it to feed its own pyromania into the machinery. Orcish Mechanics then targets Smaug the Impenetrable, whose natural indestructible nature lets it shrug off the blow while triggering its own ability to shower you in two Treasure tokens. Those very same Treasures serve as fuel for Clock of Omens, letting you untap your newly minted artifact-creature to fire the cannon all over again in an endless loop.
