MZ: Ban. I've talked at length about this but the risk/reward is completely skewed and people who talk about how you are capable of switching in and prepping your balls off for Sleep are really just missing the forest for the trees. This thing gets to spam on most of our meta, run tons of sets, always have huge reward from its high power STABs, Sleep, and two different hazards, and it's just bad to have around.
HJAD: BAN. I miscalculated in my previous vote on roserade its effectiveness as a standalone breaker, with the ability to access hazards, and instead thought it was a mon who reversed those roles. Since changing that mindset, Roserade has become much more painful to deal with, considering its large SpA, useful stabs, and ability to sleep/spike on several of the tiers more passive mons. As a result, I think it would be better for the development of the tier to remove one of the main special grass type attackers and therefore, hopefully limit teambuilding stress.
2xTheTap: Ban. The more I use Roserade, the more I understand it's simply too strong for the meta. Firstly, the way it takes advantage of the more defensive portions of the meta, ex. Aromatisse, Jellicent, Vaporeon, Gigalith, Palossand, Regirock, Runerigus, Lanturn, etc. (basically our primary checks to the tier's Fire-, Flying-, and Fighting-types), makes it very difficult to build coherent teams that address as many threats as possible without losing to Roserade or one of the breakers that Roserade enables (ex. Passimian, Archeops, Magmortar, etc.). In forcing many of these defensive linchpins out on threat of its powerful dual stabs, Roserade is easily able to create free turns that it can use to set Spikes to create a huge amount of offensive pressure, disable a switch-in with Sleep Powder, or simply Synthesis in order to threaten these defensive Pokemon more effectively in the long-term. Its sets are also variable enough (ex. Eject Pack Leaf Storm, Scarf, Specs, LO, Extrasensory, Synthesis, etc.) that playing against it isn't always as straightforward as you might think. Many of its offensive checks are fine to beat it in the short-term, but you're still playing around it with a razor-thin margin in those scenarios - having Golbat put to sleep, Charizard hit with a Sludge Bomb poison, Silvally-Steel taken to half with Specs Leaf Storm for example are things you can't really do much against when playing vs Roserade.
tlenit: Do nothing. If I had to pick suspect test mon, its Archeops.
honestly not sure what to say. None of them too much for the tier. Top tier threats for sure, but still question mark what Toxicroak is doing on this slate. Went through on latest post Virizion and Roserade and thats pretty much all I have for them.
termi: Ban. Honestly not as clear-cut of a case as many make it out to be, but at the end of the day I think it's broken. I do think Sleep Powder is a bit overestimated, sure it can bypass some of your checks but it is pretty luck-based and ultimately I think you get way more mileage out of Synthesis. The real problem with Roserade is that it completely takes advantage of the more passive side of the metagame that is needed to keep other big threats like Archeops and Passimian in check. Palossand, Jellicent, and Aromatisse to name a few are very important checks to many top threats and all let Roserade in basically for free, especially when you can get rid of accumulating chip damage with Synthesis. From there on, you can choose to set Spikes if your opponent is vulnerable to them or simply fire off a STAB move, since there's only a few actual switchins and most of them get chipped pretty easily.
Specs: Ban. With the tier slowed down post Duraludon, Indeedee, Raichu-Alola, Tauros, ect. Roserade has become too much to handle. Its spikes became more reliable, its already fast sleep became tougher to outpace, and its breaking power became more noticeable. With the fighting craze going on, it also isn't tough to get in. Fairys like Aromatisse and Whimsicott, and bulky waters like Jellicent and Vaporeon allow Roserade in scott free for most of the game. TlDR it's has too many ways to get in, and once it is in it's very tough to stop because of sleep.
Ktütverde: Ban. Roserade has too many things going for it. The combination of them all makes it completely broken. The first combo is it's insane special attack paired with its ability to abuse staples such as defensive waters, rocks and grounds (except gigalith that has massive spdef and high attack). That gives it the ability to click Leafstorm 2 or even 3 times per battle, and nothing can stomach this except subpar, passive options like Golbat and Articuno. Remember that Roserade is pretty much as powerful as Latios, and that our steels are far less bulky than OU steels. Useless comparison maybe but I like it. Then there are poison types but they don't like switching into roserade at all, especially since they have to be run physically defensively to check fightings: Weezing, Garbodor. Then the second combo is spikes+sleep powder, the latter move allows roserade to prevent defoggers from removing spikes: if roserade didn't have access to sleep powder, the likes of steelvally and poisonvally could be able to pressure it and remove all spikes quite reliably. But with sleep powder, they become useless. I didnt mention roserade's speed, which is pretty good, and lets it outspeed a bunch of threats that would otherwise beat it like toxicroak gallade hitmonlee and garbodor. My conclusion is that roserade is too powerful for PU, abuses staples and can make use of spikes too easily to be allowed any longer in the tier.
ManOfMany: BAN. Roserade is still too much for the tier. I feel like people still continue to underestimate Leaf Storm and Bomb from 125 Special offense, that hits like a truck. If we had better steel types I might feel differently, but Roserade can simply click Sleep Powder on all of them but Ferroseed or set up hazards on the switch.... or set up hazards while they are sleeping and go to the plentiful steel switch-ins that are on teams these days. Because of this, the Roserade user can easily maintain momentum even with counterplay on the field. Offensively Rose is bad enough, and the cherry on top is that Roserade gets plenty of opportunities to switch in the field for relatively free. In this meta, pokemon like Palossand, Vaporeon, Regirock are defensive necessities to prevent other pokemon from sweeping teams and Rose can get in on them for balance easily. Rose does have common counterplay in terms of faster offensive pokemon but it does entirely too much work every time it comes in.
