I swear that most people who talk about dropping Ubers here, especially those who so obviously do so without knowing why they were banned in the first place, are just using it as a superiority-flexing exercise. Whether it be because they want to "know something others don't" about how Darkrai is secretly balanced or whatever, or because they fantasize about leading the charge on a new change and being seen as an innovator and revolutionary, or just because they want to be contrarian. It's a conspiracy theorist mindset coached in the language of a community for people way too into a children's video game. As with most conspiracy theorists, it is not worth seriously engaging with except to point out how little they know about the subject. It is
especially not worth engaging with when it's theorymon about a Pokemon that hasn't even been released yet.
In an attempt to spark a more fruitful conversation, I have a question: how do you decide between Amoonguss and Slowking-Galar in the teambuilder? While there's obviously a lot of differences between these Pokemon, with Amoonguss having access to Spore and Clear Smog but lacking Chilly Reception and having lower overall damage output, I feel like they typically end up serving a similar role of "specially bulky Poison that is less passive than Toxapex and can cripple switchins with status". Their resistance profiles also feel quite similar, and both naturally synergize well with Pokemon like Ting-Lu, Garganacl, Rotom-Wash, and Heatran.
In my personal teambuilding, it really feels like I decide based almost entirely on "Am I weaker to Zapdos or to Knock Off Valiant?", which is obviously a fairly one-dimensional way to judge the merits of this pair when there are a lot of very tangible differences between the two.
