Pao: 5 (quickban it)
Garg: 2 (I understand people arguments for the ban, but I don't support it)
Gholdengo: 2 (same as above)
Espathra: 1 (not a problem at all)
(3 would have been "I'm okay regardless if it gets banned or not" and 4 would have been "I understand people arguments for not getting it banned, but I don't think it's healthy")
I've already said it multiple times, but Pao is absolutely broken and a pain in the ass to deal with. The only way to actually tank a couple of hits is running Azumarill or the 2 Tauros, any other mon relies on prediction and can get absolutely destroyed by either Icicle Crash or Crunch. Even Azumarill is not a reliable answer to it: Banded Crunch from Pao is a guaranteed 3HKO if it has a Jolly Nature and Azumarill is offensive with max HP/max Atk; it's a guaranteed 2HKO
if Pao is Adamant, regardless if it Tera'd or not, meaning that you'll never be able to get a free switch in. Even if Azumarill is max Def/max HP, Adamant Pao still 3HKOs it, which is simply nuts. This is even worse when you consider the fact that Azumarill doesn't get a reliable form of recovery. This same reasoning applies to all other "checks", which all get 4HKO'd at worse if it's Jolly (Tauros as well, which still doesn't get any form of recovery and has an incredibly specific niche). And Pex can only scout for the hit just to switch out afterwards, considering that it gets 2HKOd by Adamant Crunch.
Garg is very annoying to deal with if you don't run Covert Cloak, but I don't think it's banworthy at all. It's a very good hazard setter and a nice defensive wall, but it still gets threatened by the likes of Great Tusk, which can take Salt Cure pretty well thanks to Leftovers, regular Gholdengo with Recover (most sets are Tera Fighting/Ghost/Flying, all of which lose the Salt Cure weakness and can recover even more easily) or Choice+Trick, Calm Mind Hatterene, Meowscarada, Iron Valiant with CC, Breloom and the common wall breakers like Pao etc. Sure, it can change its type with Tera, but doing so means that your opponent won't be able to Tera anything else, and considering that the most common Teras for Garg are Water and Fairy it can still get checked/revenge killed by Gholdengo, Meowscarada, Breloom, Iron Moth, Amoonguss, Specs Valiant with thunderbolt and many others. And if your team happens to run Covert Cloak then it's completely over, you get a free switch in and wall it forever. The argument that Covert Cloak is too specific of an item doesn't stand imo, considering that not only is it a good item overall thanks to the fact that it negates stat drops and secondary status effects, but it's also way more easy to slap on a mon during teambuilding.
Gholdengo is one of the best mons, if not the best mon, on the tier right now. Not only does it have a stupid good ability, but it's also incredibly versatile and, just like Lando back in the day, it can very easily run any set you want to fit in your team perfectly. You need a Scarfer? Boom, slap a Scarf on it and it outspeeds every other non-Scarfed mon in the tier besides Iron Valiant with Booster Energy and Swift Swimmers. You need a good special wall-breaker? Specs is the perfect set for you. Both of these sets can run Trick to invalidate stall and punish defensive walls that may switch in on it. You want a more bulky set with Recover? You can either use a more balanced Gholdengo with Nasty Plot + 2 attacks or go fully supportive and run Thunder Wave + Hex, both of which are very good and are rising in popularity lately. Its incredibly good ability, crazy good typing and the fact that it's a requirement for hazard reliant teams just make it omnipresent in the current meta. Is it perhaps over-centralizing? One could easily argue that, but I just believe that it suffers from the Lando-syndrome, being so good and so consistent that it can get slapped on any team without necessarily meaning that it's broken. I think that we should wait for Home to get released before actually doing a suspect test, I'm sure there will be many more mons that will be able to check it more effectively in the future.
I actually used to think that Espathra was broken in the early days of SV, but I ended up realizing that it's just too inconsistent to actually be a problem. Not only does it need multiple turns to be a threat and snowball, but Gholdengo checks it (half of the teams use it), Kingambit checks it, Hatterene checks it with Psyshock, Chien-Pao outspeeds it at +1 and doesn't die unless Espathra has Focus Blast (also it gets sucker punch) and Ting-Lu can just Whirlwind it away.
