Voltaic Construct + March of the Machines + The Eternity Elevator

Voltaic Construct

March of the Machines

The Eternity Elevator

How it works

1. Activate The Eternity Elevator by tapping it, adding CCC.
2. Activate Voltaic Construct by paying 2, untapping The Eternity Elevator.
3. Repeat.

This clever loop turns The Eternity Elevator into a self-contained power plant by using its own generated mana to fuel Voltaic Construct, which untaps it to repeat the process. Crucially, March of the Machines provides the passive foundation that glues the whole engine together: because it transforms The Eternity Elevator into an artifact creature, it becomes a legal target for Voltaic Construct's untap ability. With the statutory activation cost entirely covered by the Elevator's initial yield, you are left with an endless surplus of both colorless and colored mana to completely take over the game.
