Toph, the First Metalbender + Urborg, Tomb of Yawgmoth + Staff of Domination + Dictate of Karametra

Toph, the First Metalbender

Urborg, Tomb of Yawgmoth

Staff of Domination

Dictate of Karametra

How it works

1. Activate Staff of Domination by tapping it, adding as it's a Swamp land due to Toph and Urborg
2. Dictate of Karametra triggers, adding .
3. Activate Staff of Domination's first ability by paying 1, untapping it.
4. Repeat.

This elegant loop transforms your artifact infrastructure into a self-sustaining engine, fueled by Urborg, Tomb of Yawgmoth turning every land—and by extension, every nontoken artifact via Toph, the First Metalbender—into a Swamp capable of producing black mana. When you tap Staff of Domination for mana, Dictate of Karametra doubles your output by triggering whenever a land is tapped for mana, providing the exact surplus needed to fund the Staff's untap ability. By continuously tapping and untapping Staff of Domination, you generate infinite black mana and draw your entire deck, opening the door to infinite life and the untapping of all your creatures.
