Voltaic Construct + Sydri, Galvanic Genius + Everflowing Chalice

Voltaic Construct

Sydri, Galvanic Genius

Everflowing Chalice

How it works

1. Animate Everflowing Chalice using Sydri.
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 clever setup turns unassuming mana rocks into an endless engine by using Sydri, Galvanic Genius to temporarily grant creature status to Everflowing Chalice, provided that the chalice carries enough charge counters to produce more than the two mana required to untap it. Once the chalice is alive and tapping for sufficient energy, Voltaic Construct steps in to continuously reset it for a modest fee of {2}. The result is a self-sustaining loop that floods your mana pool with infinite colorless mana, ready to fuel whatever devastating X-spells or artifact synergies you have waiting in formats like Commander, Legacy, Oathbreaker, and Vintage.
