This thread was originally called M2K combo, which was short hop double fair, forward B B B downB, into tech chase with Fair to tipper F smash, but later I learned that doesn't work cuz of super small stun time, so I made this thread about random Marth stuff you guys can read. So don't even bother trying it cuz it only worked like the 2nd hour I had the game.
I like to do forward B B B upB at 0, then chase their double jump with full jump tipper fairs off the level and go wayyyyy off then edge hog their up B vs some chars. It's a good way to make them waste their jump and aggressively edge guard/gimp them. However, this only works if you're close range, otherwise they are able to DI away from the forward B combo and the last hit won't hit.
Ken combo doesn't work on good people at all, if it does they messed up, it doesn't combo at all though. The only "legit" way it can work is to dair them after they air dodge, otherwise it's escapable.
