Voltaic Construct + Pyramid of the Pantheon + Xenic Poltergeist

Voltaic Construct

Pyramid of the Pantheon

Xenic Poltergeist

How it works

1. Animate Pyramid of the Pantheon using Xenic Poltergeist.
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.

By utilizing Xenic Poltergeist to animate Pyramid of the Pantheon, we turn our mana-producing monument into an artifact creature capable of being targeted by Voltaic Construct. Once the Pyramid is awakened, tapping it for three mana easily pays the two generic mana required for the Construct's ability to untap it, leaving a net profit of one mana each cycle. This clever three-piece machinery lets you repeat the loop endlessly to generate infinite colored mana right on the spot.
