I was CC. I peaked at around 1240 from what I remember, though you sure wouldn't know it now since I'm at 1096--I kind of gave up on hitting 1400 after a while, and after that point I was just playing for fun with some random experiments, so that hurt me a bit. Anyway, nominations:
Manaphy
I know it's auto-nominated. I have to mention it anyway because this is the only thing that gave me issues on a rain team aside from the one Floatzel I saw (being able to attack on both sides made it so much more dangerous than every Kabutops and Ludicolo) and the odd Toxicroak. While I choose not to nominate Rankurusu, I understand why others are doing so since I primarily used a stall team and it killed me dead every time. Manaphy, though, is like Rankurusu on steroids. It does take damage from entry hazards and Leech Seed, but compensates for that by being bulkier, being faster, healing more with Rest, not needing a 70% accurate move for coverage, and not being affected by paralysis. Calm Mind is a particularly scary version of it.
Deoxys-N to OU
This was banned on theory when nobody used it. Bring it back for a real test. I could theorymon out about how Scarf Deoxys outspeeds stuff like Timid Swift Swim Kingdra, but that would make me part of what I see as a problem.
Aldaron's proposal
I hesitated on this, but in the end I support it.
Personally, I don't want to see Drizzle + Swift Swim banned, nor Drizzle alone, nor Swift Swim alone. I did decently enough with a team where four out of my six Pokemon were actually weak or functionally weak to at least one type out of Water and Ice (Skarmory's Special Defense is bad enough that it can't handle Water despite the lack of weakness)--and granted that the other two members of my team were Rain Dish Ludicolo and Nattorei, but it suggests to me that rain isn't an insurmountable obstacle when I only have two things that can really handle it and yet still have more trouble with balanced and sand.
More importantly, though, Manaphy plays such a large role in the success of rain teams that I believe it's not right to rush through and make any second simultaneous decision about rain. However, it's obvious that the community most likely will make a second simultaneous decision about rain, so I support Aldaron's proposal for lack of a better option. If nothing else, it should promote diversity by retaining the viability of RD Ludicolo, RD Tentacruel, Toxicroak, and likely others that I didn't run into.
Other stuff I'm not nominating:
I'm iffy on Latios. Often it felt like a match came down to whether I got my Latias in sooner or my opponent got their Latios in sooner, but enough things outspeed him in weather that I'm not too inclined to nominate him yet. His sister is a different story, as her extra bulk really lets her use that beautiful and otherwise-untapped set of resistances that helps check utter beasts like Rankurusu, which provides solid value in the metagame while also not being overpowered. Her Specs Draco Meteor also doesn't ruin basically everything. My Rain Dish Ludicolo could do a great job walling her (assuming no Calm Mind) and Specs Kingdra, but with Latios it's Blissey or bust for walling. Again, though, I don't see him at suspect level yet because he's possible to revenge with weather or Tyranitar, which are everywhere.
Sand teams frequently wrecked me. Had nothing to do with Dory and Landlos, though--Terakion, Heatran, and especially Rankurusu were the powerhouses there. Even Tyranitar and Scizor were scarier than the mole and the genie, but maybe that's just how my team construction went. I nominate none of these, though Rankurusu is closest.
