>>30985390Ok so I would recommend something like this:
http://pastebin.com/V6a2Nu5ZExplanations:
Poliwrath is pretty straightforward, it runs the boosting move, two strong STABs, and protect.
If you're willing to breed for a modest nature Pelipper I believe Modest sash to be one of it's stronger sets (it's been pretty successful on double duck teams recently). Moves are again straightforward, EVs are to maximize damage so you can kill shit with hurricane.
Tapu Bulu deletes gastrodon / other bulky waters which your rain duo could struggle to break, plus it helps against Tapu Koko. Wood Hammer, Horn Leech, and Protect are pretty important for providing 1) raw damage output 2) sustain 3) being the most important move in doubles. Last slot is somewhat flexible - I use substitute on a somewhat similar rain team because often times people will double protect to stall out the last turn of tailwind, giving you the chance to sub for free. Miracle Seed lets you get even more power out of your wood hammers, the speed puts you comfortably above base 130s in tailwind so you should also outspeed most scarf stuff.
Porygon2 provides the most reliable way of denying Trick Room - reversing it with your own Trick Room. It's also crazy bulky and gives you a safe switch against various attackers. Trick Room, Recover, and Eviolite are all mandatory - the other moves can be any two of toxic, tri attack, ice beam, thunderbolt, and shadow ball, and EVs can be tweaked if you want more bulk on one side of the spectrum.
Muk destroys Bulu and Lele (especially under TR or tailwind). It's also just a generally good pokemon with solid bulk and typing and being one of the few knock off users in the format. Poison Jab, Knock Off, Protect, and Gluttony+Iapapa are mandatory. Last move is kinda filler, can be just about anything you find useful. EVs are from Wolfe's London team I think, can probably be changed.
Not enough room to finish, will make second post.
