Voltaic Construct + Sydri, Galvanic Genius + Sceptre of Eternal Glory

Voltaic Construct

Sydri, Galvanic Genius

Sceptre of Eternal Glory

How it works

1. Animate Sceptre of Eternal Glory using Sydri.
2. Activate Sceptre of Eternal Glory by tapping it, adding three mana of any color
3. Activate Voltaic Construct by paying 2, untapping Sceptre of Eternal Glory.
4. Repeat from step 2.

This clever three-card engine transforms a simple mana rock into an infinite powerhouse. By using Sydri, Galvanic Genius to animate your Sceptre of Eternal Glory into an artifact creature, you enable it to be targeted by Voltaic Construct's untap ability. Once the Sceptre's heavy-hitting second ability taps it for three mana of any color, you simply feed two of that mana back into Voltaic Construct to untap it, netting a clean profit of one mana with each loop.
