Hihi - I won't comment on the pokemons you chose, but I shall comment on some stuff I saw :) Overall I like your team though - surprised to not see salamence or Garchomp, ahaha.
Why Rash on Kingdra when all you have are SpA moves on it? Modest nature would work much better in your case - and personally I'd rock Hydro Pump over surf. That added power in the rain and you'll see a difference. You can also use substitute instead of Yawn, but that's up to you. You can also consider a physical set via Chesto/rest. It's only becoming popular in 4th gen's late stages so many might not think of it.
Scizor: LO or Leftovers or CB would be better items to use :) CB and of course roost is gone for something else, lol. You can also put Rain Dance on Scizor and then have him at Damp Rock.
Jolteon: I don't like Sitrus all that much, haha.
Ludicolo: Why Fake out? Is it that useful, ie will it do any damage? lol Hydro Pump, Energy Ball, and an HP attack would be better suited, eys?
