Smaug the Impenetrable + Clock of Omens + Silverskin Armor + Orcish Mechanics

Smaug the Impenetrable

Clock of Omens

Silverskin Armor

Orcish Mechanics

How it works

1. Cause Orcish Mechanics to become an artifact using Silverskin Armor.
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 loop transforms the dragon Smaug the Impenetrable into an endless vault by leveraging the equipment Silverskin Armor to turn Orcish Mechanics into an artifact, allowing the Mechanics to tap and hurl 2 damage directly at Smaug's indestructible scales. Because Smaug the Impenetrable responds to that noncombat damage by generating two Treasure tokens, you instantly supply the exact fuel needed for Clock of Omens to tap those newly minted Treasures and untap Orcish Mechanics. By continuously looping this self-inflicted damage and untapping process, you produce infinite tapped Treasure tokens, infinite artifact tokens, and infinite artifact ETB triggers.
