How it works
Activate Karn's first loyalty ability by putting a loyalty counter on it, causing Candelabra of Tawnos to become an artifact creature until end of turn.
Activate up to six lands by tapping them, adding at least 6.
Activate Candelabra of Tawnos by tapping it and paying 1 due to Agatha of the Vile Cauldron, untapping the up to six lands.
Activate Staff of Domination's third ability by paying 3, untapping Candelabra of Tawnos.
Activate Staff of Domination's first ability by paying 1, untapping it.
Repeat from step 2.
Once you have infinite mana, you may use it to activate Staff of Domination's other abilities.
This clever loop transforms a humble artifact into a mana-generating powerhouse by turning Candelabra of Tawnos into an artifact creature using Karn, the Great Creator's first ability. Because it's now a creature, Agatha of the Vile Cauldron steps in to drastically reduce the cost of its untap ability, allowing you to untap a massive cluster of lands for just one mana. To keep the engine running, Staff of Domination serves as the ultimate utility hub, using its untap abilities to simultaneously ready the Candelabra and itself over and over again. Once you are generating infinite mana, you can easily pivot that exact same Staff of Domination to draw your entire deck and gain infinite life, sealing the game on the spot.
