Voltaic Construct + Pyramid of the Pantheon + Tezzeret, Betrayer of Flesh

Voltaic Construct

Pyramid of the Pantheon

Tezzeret, Betrayer of Flesh

How it works

1. Animate Pyramid of the Pantheon using Tezzeret, Betrayer of Flesh.
2. Activate Pyramid of the Pantheon by tapping it, adding three mana of any color
3. Activate Voltaic Construct by paying 2, untapping Pyramid of the Pantheon.
4. Repeat from step 2.

This brilliant engine transforms a humble monument into a self-sustaining mana generator by leveraging Tezzeret, Betrayer of Flesh to animate Pyramid of the Pantheon into an artifact creature. Once animated, Tezzeret's passive ability reduces the cost of the pyramid's first artifact activation each turn, allowing its mana-producing tap ability to be activated for free. This leaves you with enough mana left over to fund Voltaic Construct's untap ability, which resets the pyramid so you can tap it again for a net gain of mana.
