I think m2k and anyone off that level win as much as they do simply because they're smart. He always seems to be one step ahead of his opponent make the right decisions.
Yhea man I beleive you, and I'm not saying that anyone in this thread is just basing his opinion off of m2k's or anything like that. it's just that... before m2k made his statements, most people seemed to think that it was in marths favor. now noone does >.>
sadly you can't waveshine combo marth properly in PAL

. No jones tho, I seriously don't think it makes that much off a difference.... I usually go for just the grab anyway, and there are other things you can do out off arials then shine (jab, grab, reverse utilt...)
Anyway, I think the matchup is in Marths favor for two main reasons:
1. If he hits you with something it can often lead to a grab, and he can pretty much kill you from a grab. FD is obvious. On other stages he'll cg you until you reach a platform and then he'll start gaying you with tippers and utilts.
Marth can kill fox if he gets a grab. If fox gets a grab he gets 1 free hit (ok it's a little better then that since people don't always di perfectly every time so you can sometimes do 2 uairs and lasers). Marth wins.
2. Approaching. Sure you have the lasers, but this isn't peach you cant run away and spam all day without him catching up.
I find approaching him almost impossible, he seems to have some kind of devastating counter to pretty much everything you have.
So, ok, dont approach, laser and have him approach instead.
His approaches are to hard to punish due to low lag and range. If I try punish something like his auto canceled nair or shffl'd fair he can usually do something before I can reach (dash away, roll, spot dodge, jab, utilt..). If I try to time it earlier I'll just run into the fair/nair hitbox
Sure you have some good shield approaches but I find them very risky since they can just grab you. Marth has way more safe approaches then that
I think this matchup is way harder then falco. Sure falco can **** your *** off with shine combos but you can **** his *** off with your grabs so it's pretty even. Also fox is (much) better at getting around the lasers then most other chars are. Edgeguarding him with fox is to easy. I'd even say that fox is better at gimping falco then sheik or marth is.
Not trying to claim that this is right and you guys are wrong btw. in fact im sure that almost all of you have more high level experience in this matchup then I do... feel free to correct me somewhere.
hell if you think that im wrong somewhere and im simply not playing the matchup right and/or not punishing things that can be punished, i'd be more then happy if you told me how it should be done.
