Voltaic Construct + Thran Forge + Alena, Kessig Trapper

Voltaic Construct

Thran Forge

Alena, Kessig Trapper

How it works

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

This clever loop transforms Alena, Kessig Trapper into an artifact creature with the help of Thran Forge, allowing her to tap for a surplus of red mana based on her boosted power. Once she is an artifact, Voltaic Construct steps in to untap her for a modest investment of two mana, leaving you with a net gain of red energy each cycle. Because Voltaic Construct's untap ability targets *any* artifact creature, it effortlessly resets Alena, Kessig Trapper for another activation, fueling infinite red mana and endless artifact creature untaps.
