While checking some card spoiler from the upcoming Aether Revolt set, I have come up with this decklist for the Jund (Red/Green/Black) version of Energy aggro. I believe on the potential of the new constrictor and Rishkar to be a powerful curve in the deck. Here below is the decklist:

Jund Aggro Energy

4 Greenbelt Rampager
4 Servant of the Conduit
4 Voltaic Brawler
4 Rishkar, Peema Renegade
4 Winding Constrictor
2 Glint-Sleeve Siphoner

4 Attune with Aether
4 Harnessed Lightning
4 Unlicensed Disintegration
4 Smugglers Copter

4 Aether Hub
4 Blooming Marsh
3 Game Trail
2 Foreboding Ruins
3 Forest
2 Mountain
