Aphetto Alchemist + Staff of Domination + Chromatic Orrery

Aphetto Alchemist

Staff of Domination

Chromatic Orrery

How it works

1. Activate Chromatic Orrery's first ability by tapping it, adding 5.
2. Activate Aphetto Alchemist by tapping it, untapping Chromatic Orrery.
3. Activate Staff of Domination's third ability by paying 3, untapping Aphetto Alchemist.
4. Activate Staff of Domination's first ability by paying 1, untapping it.
5. Repeat.
6. Once you have infinite mana, you may instead use Chromatic Orrery's second ability to draw infinite cards, or use any of Staff of Domination's other abilities.

This elegant loop turns the raw power of Chromatic Orrery into a self-sustaining engine by utilizing its five-mana production to fund both Aphetto Alchemist and Staff of Domination. While Chromatic Orrery provides the necessary pool of mana, its color-filtering passive ability ensures you can always pay the specific costs required by the other permanents. Aphetto Alchemist handles the heavy lifting of untapping the Orrery, and the versatile Staff of Domination steps in to untap the Alchemist while untapping itself along the way. Once this trio is humming, the Staff's remaining abilities easily scale your infinite mana into infinite life, card draw, and total control.
