These kinda bum me out.
Because you can only cycle attack animations in the Pokemon summary screen, and you can only show special forms (megas, Aegis stances, etc) in the dex screen, you can't ever capture a solid chunk of the animations.
And that's to say nothing of there being no catalogue in-game of entry, damaged, and faint animations, which is a bummer because a few (like Mega Banette) are really cool.
