I don't know about you guys but my new favorite character after unlocking him is Wolf. I like him because he resembles Fox but is stronger in my experience. That's a great combo in my opinion. I don't have a top 10 because I played through the Subspace adventure and used almost everybody so I'm not sure how each one fights individually. I like Meta Knight and Ike because I like swords, but I also like Lucario 'cause I like being different occasionally. Personally I've had a difficult time getting used to using Olimar at all so I can't rate him. I don't think there is a "top10best" maybe there's a "top10easiestcharacterstobesuccessfulwith" but if you play enough you can win with anybody. End.
