Voltaic Construct + Karn, Silver Golem + White Lotus Tile

Voltaic Construct

Karn, Silver Golem

White Lotus Tile

How it works

1. Animate White Lotus Tile using Karn.
2. Activate White Lotus Tile by tapping it, adding at least three mana of any color.
3. Activate Voltaic Construct by paying 2, untapping White Lotus Tile.
4. Repeat from step 2.

This clever loop turns your standard artifact ramp into a powerhouse by leaning on Karn, Silver Golem to temporarily animate White Lotus Tile into an artifact creature. Once it's a creature, you can tap it for a hefty sum of mana based on your shared creature types, which more than covers the activation cost needed for Voltaic Construct to untap it. Because Voltaic Construct is itself an artifact creature, you're left with an infinite supply of colored mana to fuel the rest of your game plan.
