wth marth is easy? fox is much easier to win with than marth <.<; falco i have more trouble with but i just recently decided i was gonna get good with him lol. marth has less tech skill but tech skill isn't hard to get down, really.
honestly, play anyone you like. if you like dk go dk... learn a few if you like... for me i'm trying to decide on a fastfaller, a floaty, and a low tier that i enjoy playing as/can do well as. leaning towards falco/either marth jiggs or peach/not a ****ing clue atm. really narrowed it down i know :D
falcon, ganon, icy's, and doc all can do real well in tourneys. dk is the coolest character in the game. link's got cool combos. if you can do real well as dk or link everyone will love you even if you don't win tourneys :D
