Trazyn the Infinite + Voltaic Construct + Dreamstone Hedron

Trazyn the Infinite

Voltaic Construct

Dreamstone Hedron

How it works

1. Activate Trazyn using Dreamstone Hedron's ability by tapping it, adding CCC
2. Activate Voltaic Construct or activate Trazyn using Voltaic Construct's ability by paying 2, untapping Trazyn.
3. Repeat.

This clever loop turns your graveyard into a powerhouse by letting Trazyn the Infinite inherit the activated abilities of every artifact resting there. With Dreamstone Hedron in the graveyard, Trazyn gains the ability to tap for three colorless mana, which more than covers the activation cost needed to channel Voltaic Construct. By using that mana to pay Voltaic Construct's ability to untap Trazyn, you can repeat the process indefinitely to generate infinite colorless mana.
