Toph, the First Metalbender + Candelabra of Tawnos + Uthros, Titanic Godcore

Toph, the First Metalbender

Candelabra of Tawnos

Uthros, Titanic Godcore

How it works

1. Activate Uthros by paying and tapping it, adding for each artifact you control.
2. Activate Candelabra of Tawnos by paying 2 and tapping it, untapping Uthros and Candelabra of Tawnos as it is a land due to Toph.
3. Repeat.

This ingenious loop relies on Toph, the First Metalbender to fundamentally transform your battlefield by turning all of your nontoken artifacts into lands. With that crucial permanent type change in place, Uthros, Titanic Godcore suddenly becomes a massive mana engine once it reaches its station threshold, tapping to generate an enormous wave of blue mana scaled to your artifact count. You can then channel that bounty directly into Candelabra of Tawnos, which exploits its newfound land status to untap Uthros, Titanic Godcore, the Candelabra itself, and any other artifact-lands you control. By cycling this activation repeatedly, you easily generate infinite blue mana and infinite untaps across your entire setup.
