Voltaic Construct + Pyramid of the Pantheon + March of the Machines

Voltaic Construct

Pyramid of the Pantheon

March of the Machines

How it works

1. Activate Pyramid of the Pantheon by tapping it, adding three mana of any color
2. Activate Voltaic Construct by paying 2, untapping Pyramid of the Pantheon.
3. Repeat

The magic behind this setup relies entirely on March of the Machines, which breathes life into your noncreature artifacts by turning them into artifact creatures equal to their mana value. Once Pyramid of the Pantheon is animated into a creature this way, it can produce a massive surge of three mana. You simply funnel two of that mana into Voltaic Construct's activation cost to untap the Pyramid, keeping a profit of one mana with every single loop.
