Voltaic Construct + Kydele, Chosen of Kruphix + Memnarch

Voltaic Construct

Kydele, Chosen of Kruphix

Memnarch

How it works

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

This clever loop turns Kydele, Chosen of Kruphix into a self-sustaining mana engine by leaning on Memnarch's ability to fundamentally rewrite the battlefield's permanents into artifacts. Once Kydele is made into an artifact, Voltaic Construct can target and untap her for a mere two mana, allowing you to repeatedly tap her for a surge of colorless mana that easily outpaces the activation cost as long as you've drawn enough cards that turn. It's a wonderful demonstration of how continuous type-changing effects can unlock unexpected mechanical synergies right under your opponents' noses.
