Looks very similar to what I'm running right now, except it looks a little slower. I took full advantage of pokemon with free and low retreat costs to make the most of Eelektrik's ability.
-Zoroark works insanely well in a deck like this, especially since if you run the Darkness energies to give him the extra 10 for instant KO's on Reshi's and Zeki's, he can also go for Nasty Plot if you're in a crappy situation and save you. I'd highly recommend a 2-2 line of Zoroark instead of Tornadus.
-I'd say Druddigon could probably be swapped for a Zekrom. Zekrom's just intensively better.
-And just as a fun move, you could try running Entei Raikou Legend. It's not always completely useful, but against decks like Rehiphlosion and ZPS(LMFAO always a 2-3 prize gain) you can grab some game-breaking KO's. Then if you run Max Potion, retreat it, power it up again, use a switch and go in for round 2.
