Victini: B+ ---> A-: I was always skeptical about Victini, but after trying it out it should move up. SubPuP is really effective. Power-up Punch and a strong one-two punch makes up for the somewhat low base Attack. It also has good typing that, SR weakness aside, allows it to check some very hard to handle threats (Mega Medi and Mega Gard being the most prominent of those). The only downside is that SubPuP sometimes has issues finding a place to set up a Sub, but once it does look out. It's one of those things that if you don't have a plan to handle it, it will wreck you pretty badly. Stalltini also has it's uses for checking things, but I'm less familiar with that set.
Jirachi: B+ ---> A-: Really easy to fit onto a team. U-Turn is great for the momentum and chip damage. Rocks, Healing Wish, regular Wish and T-Wave allow it to support a lot of things. It can also run a Scarf set with U-Turn and a fast Healing Wish to decent effect. The hax shenanigans are also annoying af, but we already knew that.
Tangrowth: C ---> C+: Tangrowth can be very hard to take down if you don't have a strong STAB Super-Effective attack. The AV set handles Sand offense similarly to Chesnaught while also sporting decent special bulk. It's like Chesnaught and Slowking had some kind of weird love child. Also, there's a set in the damage calculator called alexwolf's waifu. Felt that needed to be thrown out there.
With regards to the Weather sweepers moving up, I don't think any of them should move past B+. The only three things that rely on Weather in the A or S ranks are Char-Y, Excadrill and Manaphy. Char-Y and Manaphy set weather themselves, so their reliance on it matters less than Kabutops and Kingdra. Excadrill is A+ because of weather, but even without that, strong attack, good defensive typing, Mold Breaker, spinning, Rocks and a decent attacking movepool make it at least an A- threat without Sand Rush. Without Sand Rush Exca is still a decently viable OU Pokemon, without Swift Swim Kabutops and Omastar are NU.
