Roserade
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.

Virizion
Suspect. I'm going too much back and forth on this one to vote ban, I usually don't find it too difficult to be somewhat prepared for this thing, but due to its versatility and the fact that many non-passive checks you're never really truly prepared. Especially on faster teams that can't afford a momentum suck like Aromatisse or whatever it's very difficult to be prepped, and the only saving grace here is that Ribombee/Talonflame/Whimsicott all check it somewhat defensively while outspeeding it and hitting it hard with their STAB moves, although they're still pretty shaky switchins due to Stone Edge OHKOing 2 out of 3. Basically, it can probably be played around, albeit awkwardly, so for the moment I can't vote ban on it.

Archeops
Suspect. I initially found this to be too much for the tier because of its speed and attack stat paired with good coverage and amazing support move in Knock Off and U-Turn, but I'm a bit more sympathetic to the idea that it might be fine, at least enough to leave it up to a suspect test instead of a quickban. It's pretty awkward to build with due to its typing, pretty awkward to get in, has to make some tough concessions in what it can and cannot run, and obviously is greatly helped by Roserade's presence as a reliable spikestacker and switchin to several of Archeops's checks. I think it would be good to see how Archeops functions without Roserade to support it.

Toxicroak
Suspect. I nominated this one actually but I haven't seen a lot of people supporting a ban on this. The main reason I wanna keep a close eye on it and suspect it in the near future is because the strain the Fighting types put on you in the builder is crazy and I feel something has to go to make building balance without autolosing to Toxicroak or Gallade or whatever possible. NP Toxicroak especially is a problem imo, while it is not as consistent as a physical set, it beats several of its would-be defensive switchins like Palossand and Weezing, while turning Wisp Jelli from one of its best defensive checks into setup fodder. What sets it apart and puts it above Gallade and Scrafty imo is that its defensive typing and ability give it way more opportunity to break teams than Gallade on the one hand, and unlike Scrafty it does not need to click its setup move to become dangerous and has more immediate speed. Although I love using this mon I feel like it's ultimately not something we currently have the tools for, I'm just not sure enough of it yet to vote quickban.
