On a few of these I am curious
For the Mons: Rhyperior and Electivire had old Legacy moves from Community Days made available again by evolution, but having played both days, I only ever saw or saw reported Hisuian Evolutions from the "Raid 3" task (Ursaluna, Kleavor, Braviary-H, and Avalugg-H). Did you see this in a catch task, a news video, or something like a thumbnail/image related to the event? Curious if I missed something maybe from the LA Tour.
Gliscors
Ursalunas
There was another video I can't find now (I thought it was Trainer Tips but doesn't seem like it, maybe PokeDaxi? I've been on a Go-tuber kick lately) that had them run into Electivire & Rhyperior.
I found your confusion odd, so checking the wiki even that doesnt mention the Gliscor, Electivire or Rhyperior (& Serebii just talks about the global). It has Ursaluna, but only during the Space-Time Anomaly segments (shown in the video). How weird, was it an unreported addition? A Niantic Goof (TM)?
Oh I didn't know the Tour & Fests doubled up on the theme. All I remembered from the last one was Diancie. Which...kind of off theme from the Hoenn one I'd say.For Basculin-H and Basculegion, my best guess is it will show up for Go Fest (likely Sinnoh/Hisui themed again) in the Summer, much like how Tour and Fest last year were both Hoenn themed (Primals for Tour, then Primals -> Mega Ray for Fest) and had a lot of Mega themed goodies like Diancie and Carbink-dropping-Energy for that. It's the only reason I can fathom for adding Basculin but not letting it evolve yet (including an explicit note it cannot as they liked to do with the Hisuian Evolutions).
They also have JUST enough remaining Hisuian Pokemon that I could see those dotted in as well (Lilligant, Zorua/Zoroark, Sliggoo/Goodra) for side options, doubly so with Goodra to prep for a CD in late 2024 or 2025, on top of Arceus as some conclusion to the Origin Raids this time (rampaging duo -> Trio master since they want to evoke the Primal Raid benefits again) after they made an explicit deconfirmation of Arceus appearing in Tour.
The remaining Hisuis, Basculegion and then probably Phione/Manaphy & Arceus would track.
Seems like the easiest thing would be keep shelling out Cosmog research for people who can't raid, but then at the same time do Solgaleo/Lunala raids.As much as I like Alola's story, the evolving Legendaries created serious problems for Go transfer to match some clumsy Main-game appearances. Solgaleo and Lunala get appearances but in SwSh they also threw in an awkward Cosmog gift alongside the Dynamax Adventure captures, while SV just did away with it appearing while retaining its ability to be transferred. I'm convinced a similar issue is why Go refuses to do Solgaleo/Lunala raids and just has the couple timed Cosmog researches (Despite Solgaleo being pretty significant in PvP so being able to farm Candy or roll more is a big deal), and I worry Poipole is going to fall victim to the same availability issues.
People who have no part of the line then get extra encouragement to do both
Poipole is more of a "real" Pokemon to use, so they could probably get away with putting it in lower tier raids while Naganadel goes into higher tier raids, but I still suspect they'll start it with a research for some unknown amount of time.
