I'm surprised that with the predicted dominance of Mega Ray, no one has talked about Lightnings types in this format. I've heard scarce talks about using Zebstrika (Zap Zone prevents Flash Ray and things of that nature), but Lightning has some viable contenders, including Magnezone for energy acceleration, Eelektross (for moving to Active, but probably not too useful since you'd be running two Stage 2 lines), M Ampharos, Raichu and Raichu BREAK (Circle Circuit ftw), Raikou, and the aforementioned Zebstrika.
Of course, a Lightning deck would be completely crushed by Zygarde and Fighting type decks in general, even if they are losing a bit of support with Korrina leaving. This is where I mention Flash Energy, the [L] type Special Energy card that negates weakness. Circle Circuit can easily reach 100 (160 with Sky Field) and OHKO a lot of non-EX mons, and hits everyone's favorite Set Up card and everyone's favorite legend for weakness. You could tech Altaria to combat the Lightning weakness, but there are so many ways to get around that. Hex Maniac, Silent Lab, and its frail 90HP leaves it weaker than Shaymin. Lysandre it for a KO with Circle Circuit or Zebstrika's Lightning Crash (which does extra damage anyway because it has [F] resistance).
Lightning seems to have a very bright (lol) future ahead of it, with the ability to bypass weakness with Flash Energy and crush Mega Ray for weakness. Also, none of the Lightning types from Japan's Steam Siege (there are 3 Lightning types in the set, and it's just the Ampharos line) are very competitive.
