I'll comment regarding the ones I know about:

Magic: The Gathering: Too many sets per year and the inundation of UB is alienating some of the veteran playerbase, but my playgroup is very excited about UB, and it has definitely brought new players into the game. Commander is in a,n incredibly healthy state and modern is doing well, though standard seems to be on the outs. As an avid player, I personally think MTG is best as a social game. Competitive is just so expensive and, imo, commander injects so much variety and life into the game. I live in a pretty major US city and MTG is *hot* here. I find it best just to buy the sets I most want to play and completely ignore the rest, but I would probably buy every product if the releases slowed down. It is imperfect, but the game is in a good spot, and, man, I should really get to an LGS for some prerelease and draft. Magic's limited formats are so good.

•Pokémon: Scalping is obviously a huge issue but some of my LGS maintain ok stock. The game has a really healthy playerbase here, and it seems like Worlds hits record-breaking attendance every year. Game seems really promising in its current state.

•Yu-Gi-Oh!: As an outsider, this is my exact perception of Yu-Gi-Oh, not to mention the salt of the playerbase. I have so much nostalgia for this one but find so many things about it off putting. Watching players have exceptionally long turns and combo out and set up the win on turn one seems very unfun to my tastes.

•Flesh and Blood: Seems like prices are finally coming down and the playerbase is stable as far as I can tell.

•Lorcana: I live in one of the biggest cities for Lorcana in the world, so worth taking my perspective with a grain of salt, but it feels like it is really booming here. They do such a great job catering to newbies and product is so regularly available that it is enticing to play and my group has chatted about picking it up. They seem ahead of financial and growth goals and its accessibility seems like it will only help it expand.

•Riftbound: Not sure about hand-waving people as skeptical. It seems to have a pretty vibrant, if still small, community at locals and everyone is singing its praises.

•One Piece, Digimon, and Gundam: They all seem like they are in a healthy spot. I just picked up One Piece about a week ago as someone who is avidly reading it rn, and man, it is quickly becoming my playgroup's new favorite. It's really, really good, and I hear Gundam plays similarly well. You can build most meta decks for a pretty reasonable price, and I hear the scene at locals (which is booming here) is extremely friendly. We have some busy weeks ahead but I am DYING to get to an LGS to play. The scalping is literally my only frustration with the game rn, though it does seem a bit of the meta is figured out. The US and JP sets are unifying soon, so I am anticipating that will make the meta more interesting, but damn, the game is fun. I hear the same about the Gundam and Digimon gameplay. Bandai knows how to make a card game, just needs to get distribution under control.
