I'm super hyped about Slowbro-Galar, I was speculating it to be part Poison (although I was surprised to see it being the primary typing fsr) since they showed it and it makes me happy. Dunno how it'll perform competitively since while it's a good Clef switchin it doesn't get Teleport unlike its Kantonian counterpart, but I really hope it's usable in UU; assuming it keeps Regenerator, its AV set is a direct improvement from AV Reuniclus (checking offensive Fairies and Rose) while being a better physical tank. It'll play very differently to regular Bro even if they share the same stats though, since it can't check Grounds or Darmanitan. Still pretty cool.
I'm also sad that Zapdos lost its Electric typing, Electric/Fighting would've been a very interesting combination. Articuno-Galar looks interesting Competitive-ly (lame pun, sorry) even if I like the others' designs more. A Psychic-type move that freezes is something I wasn't expecting at all.
Anyway, I'm really happy with the news and can't wait to try the new stuff. Grassy Surge Gorilla also seems fun, especially if the new Grass-type move ends up being physical. Good stuff.
