Agatha of the Vile Cauldron + Magus of the Candelabra + Staff of Domination

Agatha of the Vile Cauldron

Magus of the Candelabra

Staff of Domination

How it works

1. Activate up to six lands by tapping them, adding at least 6.
2. Activate Magus of the Candelabra by tapping it and paying 1 due to Agatha of the Vile Cauldron, untapping the six lands.
3. Activate Staff of Domination's third ability by paying 3 and tapping it, untapping Magus of the Candelabra.
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, or if you have infinite and , you may use it to activate Agatha of the Vile Cauldron's ability.

This clever loop turns Magus of the Candelabra into an aggressive mana engine by using Agatha of the Vile Cauldron to slash its activation cost down to just a single mana. With those discounted lands pumping out more than enough juice, Staff of Domination steps in as the ultimate multi-tool: its third ability untaps the Magus so it can fuel the lands once more, while its first ability untaps the Staff itself to keep the cycle spinning. Once you have this infinite mana loop established, you can safely point the Staff's remaining abilities toward infinite card draw, lifegain, and locking down the board, or even pour your excess red and green mana into Agatha of the Vile Cauldron to give your entire team infinite stats, trample, and haste.
