I don't know if you already have this strategy, but here it is. You know how your Dark and Steel decks are only limited to 4 of each of the energies, well that is solved , and the Pokemon that helps, Electrode, is also pretty strong. Alls you need to do is use his Pokemon Power, Buzzap, and you can turn him into 2 DARK ENERGIES OR 2 STEEL ENERGIES, how convenient. This is possible because the Pokemon Power nevr says Basic Energy it just says energy. But that also leaves the qustion if you can turn him into 2 DOUBLE-COLORLES ENERGIES.
