Yeah, that looks pretty good (that's what I'd run) and I guess Zen Headbutt could get an honorable mention if you really want another stab or something.
+ Fire Blast / Flamethrower
Electric + Fire is a pretty cool STAB combo, especially when you consider that it has Levitate to nullify an otherwise nasty weakness to Ground. However, it's not all good for your toaster oven. The only offensive Fire-type move it gets is Overheat, which basically forces you to switch out after. Combine a weakness to Stealth Rock, and the fact that you basically have to switch after using Overheat doesn't do any favors for Rotom's lifespan.
Fire Blast would be the obvious fix, as it doesn't force Rotom to switch out, and still provides pretty good power, especially in the sun. Flamethrower gets an honorable mention in the event it couldn't get Fire Blast. One last curious option that would be interesting is Eruption, but it wouldn't be easy for Rotom-H to take advantage of it.
+ Surf / Water Spout
Electric / Water typing is fantastic, and everyone knows how good Rotom-W is. The only downside is that its only option for a Water move (ignoring HP Water) is Hydro Pump, which has good power, but holy fuck, is it annoying when it misses. Surf would be much more reliable, and still quite effective, given the prevalence of Rain.The other option would be Water Spout, which needless to say, would pack quite a punch in the rain. Unlike Rotom-W
I think you mean Rotom-H there it doesn't have a weakness to floating rocks, and would be able to abuse Water Spout much more effectively.
Ah, Rotom-S. Another target of Gamefreak's sadistic trolling, is the only flying type with Levitate. On a more positive note, Electric / Flying is fantastic, and unlike Zapdos, it gets a somewhat decent Flying move in Air Slash. However, while Air Slash can be useful for infuriating your opponent with flinches, doesn't have a whole lot of power behind it, which is where Hurricane comes in. High base power, an excellent side-effect, and splendid coverage with its primary type, Rotom-S could very easily abuse this in higher tiers by taking advantage of Politoed's permanant rain, and spam Thunder and Hurricane, or set up its own rain in the depths of NU, and obliterate an opponents team.
