holy ****, its Roager! That guy's been gone for a while. Too bad, really, cuz I liked that guy.
Anyway, yeah, I'm here, dunno how long I'll stay, but here's my fox matchup stuff.
Fox has Falcon outmatched, in most every way. Except in killpower and (in some cases) range.
So, what do you do against a fox? Well, I don't know a lot about Fox metagame, but his Dair is **** useful. Against a Fox Dair, your best bet is to sheild, then try and roll away when he lands. It's not great, but it helps. Against his grabs, keep track of what he does, and DI away from his patterns. Uair, Usmash, and possibly Bair are his favorite Killmoves. (At least, they're my favorite fox killmoves)
Anyway, there's very little you can do about those, except that they all have long (for fox) post-lag. This is your one and only chance to punish fox. Seriously. Ok, recovery too, but I'll get to that.
Point is, if you can land a uair or something, then you can use that to get an advantage. Tough, but not impossible.
When you manage to get fox off the edge, he has 2 options: Illusion and Fire. Illusion is crazy predictable. It will go straight to the side, the same distance every time (yeah, it can be canceled, but nobody does it) and at the same time every time but it goes really fast. Fire, inversely, is less predictable (though they will almost without fail go straight for the edgegrab) but its slower.
Both of these have punishable endlag, and particularly punishable helpless fall. Also, edgesteal at every opportunity. Fox likes to grab the edge to minimize his vulnerabilities. The only exception is when he tries to illusion past you, almost across the ground. If he tries that, sheild and pursue. Dash attack is probably the only thing you'll manage to hit with, but its something.
I'll probably come back to post more later, but right now i'm tired. So here's something.
I dunno how useful it is, but go for it.
