This thing is basically forced to run some kind of combination of Thunderbolt, Energy Ball, Dazzling Gleam, Signal Beam, Volt Switch, Tail Glow, and Hidden Power. That's not too bad.
After a Tail Glow, it can even 2HKO Chansey and Venusaur with Thunderbolt (With Modest + Life Orb). However, it gets revenge killed pretty easily if you run that... so maybe a scarf set would be beneficial, but then it can't get through defensive teams. No matter what set this thing runs, it has weaknesses, but until you know if it's going to go for Scarf or Tail Glow, it might be difficult to handle.
Still, I'm sure some more well-versed players will find a way.
