Voltaic Construct + Mycosynth Lattice + Rofellos, Llanowar Emissary

Voltaic Construct

Mycosynth Lattice

Rofellos, Llanowar Emissary

How it works

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

This elegant engine turns a legendary elf into a powerhouse of green mana by exploiting a subtle type-shift. With Mycosynth Lattice turning every permanent on the battlefield into an artifact, Rofellos, Llanowar Emissary is no longer just a standard mana dork—it becomes an artifact creature that can be repeatedly targeted. You can then use the mana generated by Rofellos to pay for Voltaic Construct's ability, untapping the elf so it can tap again for an even greater profit. Because Rofellos scales with your Forests to produce more than {2} mana each time, this loop yields infinite colored mana while leaving your artifact creatures fully untap-ready for whatever comes next.
