I used to run a Raichu/Electivire FB deck, but it's a little slow. But it does catch up especially with it's body. Also, you're going to be wanting to run Felicity's and stuff that discards energy and other stuff that attatches them from the discard so you can easily use Raichu.
Magnezone is also amazing. With Magnezone SF, you can attatch an energy to an active and then place a counter. And you can just keep doing that and keep using simpler energy restorers such as Conductive Quarry to put them into your hand and regular attatch the Metal. You just keep locking them until they get KOd, and they only have one turn before you shut them down again. Vileplume RL or Heatran X are also nice techs. I can't say it's the best deck, but it's a good electric deck.
Also, I'm assuming you don't want to play Luxray GL Lv. X varients. Because if that's not the case, you know there's always a huge collection of combos.
