Ultra Burst Necrozma:
I'm torn being both sad and glad they revealed this. On one hand I'm sad as it would have been a neat surprise, you thought Necrozma's only new form was the Dusk Mane/Dawn Wing but surprise! Necrozma reveals it's true form via something similar to Mega Evolution (GF are such hypocrites at times...)! Though I am glad... because I was spoiled on yes. Some may remember I warned you that, if you want to see the stats for Necrozma's new forms, don't as there was spoilers. This was it. So I'm glad that now I know going into the game I would have known about this. Maybe I would be a bit more excited about this trailer, but still who knows (if you don't know story spoilers) how this will manifest in the story (though if I had to guess that moment in the Ultra Recon Squad's city where we approach Necrozma on the platform it's being analyzed on and suddenly the area is bathed in light with light orbs rising out of it probably a good moment for it).
No, people remembered (at least I did as I have the USUM site's background as my computer's background so it's always staring at me), though maybe not specifically who pointed it out first.
BP & Tutors:
Huh, so you can get BP from the Mantine Surf mini-game (in the form of Beach Points)? Neat!
Drain Punch on Incineroar I guess is alright.
Does anyone really teach Icy Wind to any of their Pokemon? Not being mean, because on paper it sounds useful (especially for Doubles) but I've just never seen it.
Heat Wave has been a Tutor since Gen IV,
Aldertz.
Golisopod doesn't learn Earthquake so Drill Run is a nice addition to handle Rock and Electric-types.
Thunder Punch on Tapu Koko, it's a miracle! Now we just need Play Rough...
So, the top Mantine Surfer is "Big G" and Golisopod can lean Drill Run from tutors, hmm...
