Voltaic Construct + Faeburrow Elder + Encroaching Mycosynth

Voltaic Construct

Faeburrow Elder

Encroaching Mycosynth

How it works

1. Activate Faeburrow Elder by tapping it, adding at least 3.
2. Activate Voltaic Construct by paying 2, untapping Faeburrow Elder.
3. Repeat

With Encroaching Mycosynth weaving its transformative magic, Faeburrow Elder is granted artifact status alongside its natural green typing, turning the druid into an artifact creature that can be repeatedly targeted. This allows Voltaic Construct to step in and untap the Elder for a mere two mana, an investment easily covered by the Elder's own tap ability when it converts its boosted multicolored presence into a windfall of colored mana. By cycling these activations, you loop the untapping and tapping to generate infinite colored mana while keeping Voltaic Construct ready for any other machinery you might control.
