Voltaic Construct + Kami of Whispered Hopes + Memnarch

Voltaic Construct

Kami of Whispered Hopes

Memnarch

How it works

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

This intriguing loop transforms a humble spirit into a one-man mana engine by turning Memnarch's artifact-making ability on Kami of Whispered Hopes. Once the Kami is an artifact, its own tap ability yields enough mana to pay for Voltaic Construct's untap cost, leaving a profitable surplus thanks to the Kami's counter-boosting static ability scaling its power with every iteration.
