Who's would you change? I would change (so far) Meta Knight's, Mario's, and Jigglypuff's. My reason for Meta Knight is for a character that is so good he got banned from tournaments has ironically one of the worst Final Smashes in the game. Mario's is really easy to dodge. All you have to do is get behind him and don't go in front of him when he is using it. And Jigglypuff's has a short range, and all you need to do is go below (assuming she is on a higher platform than you) or far away from her. So, begin.
