SM OU Rain team problems

[MarowakedInThehead]

I recently got back into playing Pokemon and I thought I'd try to make some weather teams. The hail/veil team plays pretty nice but I'm having trouble with the rain team. I figured I would post on here and see if there are any quick fixes or replacements I could make. Feel free to fill me in if rain just doesn't play as well in ou anymore too.

All Pokemon have perfect IVs as I don't have any hidden powers in my set so I won't bother writing them out for each Pokemon.

Welcome to Smogon! I'm locking your RMT for the time being as the forum rules require that you provide at least 3 lines of descriptions for each Pokemon to explain their roles. Please read the rules carefully and take a look at Team Showcase to see the level of detail we require. PM me with updated descriptions and I'll be happy to unlock this.
