For the next Star Guardian skins, they should take inspiration from Symphogear
Over-the-top transformation sequences, crazy attacks, and stellar production values. It's little mystery as to why Symphogear (which just started airing another season) is so popular.
I know the Star Guardian skins are meant to emulate Sailor Moon, Madoka, and a few others, but it'd be really nifty if the next group of Star Guardian Champions could take notes from Symphogear.
My 2 cents.
