Well there are two ways to get special energy into play quickly, one is Celebi [star] which searches your deck for an energy and you can attach it to one of your pokemon and the other is the new castform [star] which attaches itself as special rainbow energy that provides 2 energies but they must be different energy. In terms of searching, Furret does it but you have to use up your attack phase.
The other method I was thinking of was doing like 4 react, 5 dark, and 4 electric and use rotom as the main energy acceleration.
I really want it to work too since it would also give me an edge against Metagross EX if that ever gets popular :<
