Voltaic Construct + Thran Forge + Axebane Guardian

Voltaic Construct

Thran Forge

Axebane Guardian

How it works

1. Cause Axebane Guardian to become an artifact using Thran Forge.
2. Activate Axebane Guardian by tapping it, adding at least 3.
3. Activate Voltaic Construct by paying 2, untapping Axebane Guardian.
4. Repeat from step 2.

This charming three-card loop transforms an ordinary defender into a tireless dynamo by leveraging permanent type-shifting alongside raw mechanical synergy. Thran Forge lays the groundwork by turning Axebane Guardian into an artifact, making it a legal target for Voltaic Construct's untap ability. Once the guardian is primed, its tap ability generates more mana than the construct requires to untap it—especially when fueled by its own defender status and the other creatures you control. By cycling mana through Voltaic Construct to repeatedly untap Axebane Guardian, you net an infinite supply of colored mana to power the rest of your strategy.
