On to new Horizons!
Agreeing with Silvershadow on the Vanilluxe and Spiritomb matters. Also, I already stated my opinions on Medicham.
Anyways. It's Rock-type time!
I know this has been brought up before, but I'd suggest Rhydon for Low or Mid A-Rank. Rhydon is pretty fucking awesome atm in RU. He is easily one of the best Stealth Rock setters in RU, as he has amazing bulk, and can check a lot of physical threats such as Absol, Entei, and a bunch of others, and can thus easily set up SR. With maximum investment into defense, even Crawdaunt's Waterfall is not OHKOing it. Rhydon is very flexible with his EV's and you can tailor the EV's to your team's needs; hell he can go for a specially defensive EV spread to check things like Galvantula and Manectric! Rhydon also has a great offensive typing, giving it STAB EdgeQuake coverage, and its high Attack also allow it to hit solidly hard. Rhydon is also an amazing wallbreaker with CB thanks to this, and if you're not looking for a tank, you can just use his pure power and coverage to break down walls for days. RP Rhydon is something I've tried as well (along with Golurk), and it's an incredible sweeper thanks to EdgeQuake coverage and high Attack. It's kinda hard to set up, but once you grab the boost, you're golden. In addition, its immunity to Thunder Wave only sweetens the deal. While its weaknesses to Grass and Water are a rather crippling flaws, those are easily patched up with the use of teammates (ahem Roselia), and Rhydon is just a really good Pokemon, and as of now I definitely think he's worthy of A-Rank.
I'd also suggest Omastar for Top B-Rank. This thing is absolutely phenomenal in the sweeping department. It's not that hard to grab a Smash boost, by coming in on something like Entei or Emboar choice-locked, and once Omastar grabs a boost, it can very easily sweep a team. Between Surf, Ice Beam, and HP Grass, Omastar attains perfect coverage, and with just hazard support alone the whole team is liable to go down. With a Timid nature, not many things can outspeed it (iirc not even Scarf Rotom-C outspeeds it), and it can just destroy everything. Overall Omastar is easily one amazing sweeper in RU and should be Top B imo.
