Some other things I like to point out.
 * Magnus is an assist trophy, and like Little Mac in SSBB has AI.
 * Both Wii Fit Trains have the exact same moveset according to Sakurai.
 * Mewtwo and Lucario's movesets were already different to begin with.
 * I never believe Waluigi was considered as Sakurai almost made fun of the people who wanted him in. However I think there was a discussion about whether to put in Rosalina or Bowser Jr.

But I would love if Fawful becomes an Assist Trophy, unfortunately he will never become a playable character but I absolutely would love it if he becomes an AT (not in the way they describe it in this leak tho)
