Gonna just say that if you played Sun/Moon then you probably can give US/UM a skip, though we'll see if things shake up in the second half of the game. First island is almost identical to the first game. Mantine surfing is pretty fun and is how BP are distributed though so it's possible (and fairly easy--surfing isn't hard and shits out a ton of BP) to get some solid tutor moves early.
I hadn't used Rowlet yet so the only set part of my final team are Decidueye and the event Dusk Lycanroc. I'm trying to use a few mons in other spots that would normally get benched, so I'ma try getting Arbok into the Hall of Fame.
