Voltaic Construct + Prismatic Geoscope + Xenic Poltergeist

Voltaic Construct

Prismatic Geoscope

Xenic Poltergeist

How it works

1. Animate Prismatic Geoscope using Xenic Poltergeist.
2. Activate Prismatic Geoscope by tapping it, adding at least three mana of any color
3. Activate Voltaic Construct by paying 2, untapping Prismatic Geoscope.
4. Repeat from step 2.

This clever loop turns your mana rocks into a self-sustaining engine by breathing life into inanimate objects. Xenic Poltergeist acts as the catalyst, transforming Prismatic Geoscope into an artifact creature whose power and toughness match its mana value. Once animated, that same Prismatic Geoscope can tap for a windfall of colored mana thanks to its domain ability, generating more than enough fuel to pay for Voltaic Construct's untap ability. By cycling the mana back into Voltaic Construct, you endlessly untap the Geoscope to repeat the process, yielding infinite colored mana to power the rest of your strategy.
