MK is my true main, but I don't use him too much anymore. I'm 90% Marth in friendlies.
Marth wouldn't do as well as you probably think by pressuring you the way MK does. Marth needs behind his sword... You'd have no problem hitting him out of his attacks if he is too close. Your Samus and jiggs can and will hit him out of his fairs if he's not spaced well. I play a pretty fast\aggressive Marth.
I am Washu-bot B, loyal servant of Final-Fan, the greatest scientific genius in the universe!
