Lol, I don't have mod powers here, /B/utterfree ;o
Also, major props to Yonko7, for his big reflection upon his laddering experience with a hard-core Rain Team >:D. That specially-defensive Escavalier rain summoner is a cool discovery, Yonko; Knock Off is certainly a nice option, although Sleep Talk may prove handy to deal with Lilligant more effectively. I'm particularly intrigued by your choice in Dry Skin LO Jynx as your Rain Abuser! Does it successfully set up on Slowking or Lanturn? Because if that's the case, we have a Pokemon that can exploit conventional Rain checks!
It's no surprise to me that Rotom was a failure in your team. I see a lot of mileage trying out a different Electric-type, such as mixed Electivire with Thunder or Manectric, since they have more versatility in wallbreaking capabilities. Alternatively, you may add another Rain Inducer, so that Ludicolo can have a free slot for Hydro Pump or Focus Blast. I suggest Volbeat, because it foils opponent's set up opportunities, while it guarantees Rain, thanks to Prankster Rain Dance - it really patches a lot of coverage issues of offensive Rain teams. Alternatively, you may even add another Swift Swimmer like Qwilfish or Gorebyss for more rain slaughter!
Finally, I can certainly agree with 2 of the Pokemon that you posted as threats - Cosmic Power Sigilyph and Ferroseed. The latter Pokemon is the main reason why I always have a Rain Abuser with a Fighting move to quickly weaken Ferroseed. Volbeat is actually nice for dealing with Sigilyph, since it can Encore either Cosmic Power or Roost, which would allow Kabutops to set up SD. I never had a problem with Moltres, though, and I doubt you'll have problems with it either if your Rain Inducers were not weak to Moltres x_x
Thanks for spicing up this thread with your priceless experience, Yonko7 - it was a good reminder that this thread is not only here for building a guide, but to also share our rainy days at the RU Ladder, lol. I hope any of my suggestions here would help you conquer the ladder again :)
