Voltaic Construct + Bello, Bard of the Brambles + The Eternity Elevator

Voltaic Construct

Bello, Bard of the Brambles

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.

With Bello, Bard of the Brambles turning high-mana non-Equipment artifacts and non-Aura enchantments into creatures on your turn, The Eternity Elevator naturally transforms into a 4/4 artifact creature with indestructible, haste, and card-drawing abilities. This lets you tap The Eternity Elevator to generate three colorless mana, which then easily funds Voltaic Construct's ability to untap the elevator. Because Voltaic Construct only requires two mana to activate while the elevator yields three, this loop leaves you with a net gain of infinite colorless mana that can then be filtered into infinite colored mana through The Eternity Elevator's massive station ability.
