Marth/Lucina ability, the arms are really small (and Marth's has a tipper so it's even more awkward), and it's kinda risky, also I haven't used Charizard and Bowsers copy ability in 4 so I just based it on my Brawl experience, Yoshi however, the range is still small, and if they pop out the egg early it puts you in a bad position, with the inhale you can inhale a Yoshi on it's double jump and let them just fall out and fall to its death.
Wario you might as well just spit them out, you rack up the same damage and you can move, DeDeDes ability, while on paper seems the same as Kirbys minus copying, you can't move while they're in your mouth.
And don't worry I'm not deflecting your input, I want that list to be something we can all agree on.
