I was wondering how about stamps of certain pokeball or assist trophies that would've worked as characters.. Think about it, are there any characters that shouldn't be assists, they should've been playable

I'm looking at Midna, Ghirahim, Zoroark, Waluigi, Snivy, & Dilion.

I have my reasons for these 6 characters. (And there's a few more that probably got ditched as playable characters..)
