Personally felt that all starters should've returned in Sword/Shield's expansion as well, but I guess there might be some reason they can't do it. Still, I do wonder if the other starters will have Tera Raids before Indigo Disk. The last one was Rillaboom and nothing else is in the pipeline for starters unless they reuse it. Maybe for Teal Disk, they would add a few starters into the data to provide them through there.
The Psychic attack that blocks healing sounds fun, but it's hard to say how much of an impact it would have. That PP-reduction attack by Galarian Slowking should sound useful, but it's got low PP itself so doesn't seem useful in practice. Now if we can have a Grass attack that does some powerful effect, like I guess a Torment-inducing Grass attack.
Thank you for reading.
