I feel kind of wishy-washy about Wishiwashi's ability. I think it would've been better for it to just be an evolution, since it disappears after a certain amount of damage and goes back to being the single fish, which I imagine is around Remoraid or Finneon in stats.
Pyukumuku's ability seems like it could be devastating to higher-level Pokemon or Electric and Grass types that can OHKO it.
Morelull is pretty cool. We haven't seen a glowy/bioluminescent mushroom before.
Team Skull seems like they could be the first villains since Team Rocket to not be after a legendary, since I'm not sure what that would have to do with messing up trials out of spite. Although now that I remember, Zygarde is apparently involved in the story in a special way, and it's supposed to protect the ecosystem. I doubt Team Skull cares whether they mess up the environment when they're doing bad things. I like the theme that was playing in the video when they were shown.
I want Alolan Raichu for my team. It's adorable and two of my favorite types. So far that's 5/6 of my team decided.
