The Underworld Cookbook + Clock of Omens + Metalwork Colossus + Worldwalker Helm

The Underworld Cookbook

Clock of Omens

Metalwork Colossus

Worldwalker Helm

How it works

1. Activate The Underworld Cookbook's first ability by tapping it and discarding Metalwork Colossus, creating a Map and a Food token.
2. Activate Clock of Omens by tapping the Food and Map, untapping The Underworld Cookbook.
3. Activate Metalwork Colossus by sacrificing the Food and Map, returning it from your graveyard to your hand.
4. Repeat.

This clever loop turns The Underworld Cookbook into a self-discard engine by feeding its discard cost directly into Metalwork Colossus, which uses its own sacrifice ability to bounce right back to your hand. Meanwhile, Worldwalker Helm acts as an invaluable multiplier, doubling every Food token creation into a generous bonus Map token alongside it. With Clock of Omens tying the whole machine together, you can perpetually tap those newly generated artifacts to untap the Cookbook and keep the cycle spinning endlessly.
