Is this the trailer with Galarian Linoone and that?

Yeah.

It's good, I'd prefer more new Pokemon rather than regional variants, but at least it's going beyond Kanto with them this time! Plus a region-exclusive evolution, which is cool.
The characters look interesting. Dunno if Team Yell are simply a cheer squad, or...? Anyway, they seem a little Team Skull-esque.
