Agatha of the Vile Cauldron + Staff of Domination + Candelabra of Tawnos + March of the Machines

Agatha of the Vile Cauldron

Staff of Domination

Candelabra of Tawnos

March of the Machines

How it works

1. Activate up to four lands by tapping them, adding at least 4.
2. Activate Candelabra of Tawnos by tapping it and paying 1 due to Agatha of the Vile Cauldron, untapping the up to four lands.
3. Activate Staff of Domination's third ability by paying 1, untapping Candelabra of Tawnos.
4. Activate Staff of Domination's first ability by paying 1, untapping it.
5. Repeat.
6. Once you have infinite mana, you may use it to activate Staff of Domination's other abilities.

This delightful loop transforms ordinary noncreature artifacts into living combo pieces thanks to March of the Machines, turning them into creatures whose activated abilities are dramatically cheapened by Agatha of the Vile Cauldron's power-scaling discount. With those cost reductions in place, Candelabra of Tawnos can untap your lands for a mere single mana, fueling a net-positive mana exchange. Staff of Domination then acts as the ultimate engine, using its own untap ability alongside its power to untap the Candelabra so you can repeat the process indefinitely. Once this intricate machinery is humming, you can easily pivot Staff of Domination into infinite card draw and infinite life to seal your victory.
