Voltaic Construct + Cyberdrive Awakener + Everflowing Chalice

Voltaic Construct

Cyberdrive Awakener

Everflowing Chalice

How it works

1. Animate Everflowing Chalice using Cyberdrive Awakener.
2. Activate Everflowing Chalice by tapping it, adding at least CCC
3. Activate Voltaic Construct by paying 2, untapping Everflowing Chalice.
4. Repeat from step 2.

This loop transforms a modest mana rock into an infinite engine by leveraging Cyberdrive Awakener's ability to turn noncreature artifacts into 4/4 artifact creatures the moment it enters the battlefield. Once Everflowing Chalice is granted this temporary creature type and possesses at least three charge counters, tapping it for three or more colorless mana easily pays the activation cost of Voltaic Construct. Paying {2} to untap the Chalice leaves you with a net profit of mana each cycle, allowing you to repeat the process indefinitely for infinite colorless mana.
