Exeggutor

Do not ban. Like I said in my vote for the last voting slate, Exeggutor might not be able to pick up steam in this meta due to the following: '...can easily be pressured as a result of its exploitable defensive typing and poor Speed. There are also many faster, splashable Pokemon with the potential to OHKO Eggy like Bouffalant, Liepard, Unfezant, etc...' And sure enough, we didn't see it at all this past week of Snake - a trend we may continue to see unless something changes for Exeggutor.
Perrserker

Do not ban. Perrserker is a great balance breaker with CB and SD sets being potent, but the number of times it can come in to wallbreak is limited by its poor Speed and how easy it is to chip down. Bulkier sets like AV suffer from wanting to check everything Steel-types are strong against defensively, but not really checking them well in practice: as a Normal resist, Perrserker loses to Bouffalant and Kangaskhan; as a Fairy resist, it can't really handle +1 Alcremie (ex. see TJ v keppy in Snake last week); and, as an Ice resist, it's blown back by Focus Blast from Mr. Mime-G/Rime, etc. The meta is well-equipped to deal with Perrserker, as you'll find one of Cramorant, Qwilfish, Corsola-G, Runerigus, Stunfisk, Pincurchin, etc. on just about every team. Off meta-Pokemon like Dubwool, Mareanie, Luxray are all fine checks to it, too, if you can afford to fit them.
Kangaskhan

Do not ban. It has a ridiculous number of potential sets that allow it to bypass most (if not all) of its defensive checks, making it difficult to prep for and easily one of the best Pokemon in this meta. We saw last week in Snake CS from Xiri, Fire Punch from keppy, Toxic from tlenit, standard Kanga from TJ, and all sets were effective in doing what they were used for. At the same time however, Kangaskhan really shines in a meta wherein successful hazard removal is difficult, but with options for removal in Avalugg, Silvally-Poison, Sandslash, Cramorant, Lurantis, Hitmonchan, etc. (+ boots) being as strong as they are, Kangaskhan doesn't really clean as well as it could late-game and often needs to find its chip needed to clean some other way. That, and Pokemon like Ferroseed, Corsola-G, Avalugg, and Runerigus really stop it from being too overbearing. I was more on the fence for this one, though, and would like to revisit voting on Kangaskhan later on.
Alcremie

Do not ban. Another top-tier Pokemon that I was on the fence for banning and will continue to watch closely. This combination of CM / AA / Rest and Aroma Veil allows Alcremie to act as an extremely potent stand-alone wincon, making counterplay to this set pretty sparse. Otherwise, it's been a healthy addition to the tier that provides great support, enabling more defensive teams to function efficiently. Generally, Alcremie has to choose between having coverage for Fairy resists or dual dancing or providing cleric support, so it's not impossible to find a check for this, ex. Klinklang, Alolan Dugtrio, SpDef Corsola-G, etc.
Pincurchin

Do not ban. Pincurchin isn't worrying by itself, and in the context of acting as a bulky check with reliable recovery to threats like Klinklang, Drifblim, Pawniard, Perrserker, Unfezant, etc., its presence is healthy for the tier. Rather, the support it's able to provide its teammates is a much bigger concern for me (Pincurchin is the scientist). The only tour results that Electric Terrain teams have had in this meta so far though is in Xiri v obii, and this one occurrence of Electric Seed-supported Swoobat cleaning late-game isn't enough evidence to declare that Electric Terrain teams are problematic enough to the point that Pincurchin would need to be banned. I look at Electric Terrain the same way as I look at rain; highly annoying, effective in the right setting and with a good match-up (and therefore the style as a whole needs to be considered when building), but ultimately, Pincurchin (and as an extension, Electric Terrain-based teams) is not banworthy at this time. If I see Electric Terrain teams being overbearing in other high level matches, I would be open to banning Pincurchin later on, but Xiri v obii could turn out to be nothing more than a one-off.
