i dont think fox is top tier material. btw does mk have any bad matchups now?
Hard to say if he does or not.
Still pretty early in the Brawl+ scene, so matchups could change at any time with more little tweaks to characters movesets.
With the current codeset it is still hard to say because there isn't a large tourney scene, nor have we really seen top level MK's play B+ so its hard to say how somebody like Tyrant, Spam, Dojo or M2K would play MK in B+. But more top players are playing Brawl+ as time goes on. Chu, Boss, G Reg, Ninjalink, so it is only a matter of time until we see that happen.
From my experience I'm beating MK more than I loose with my Wario, but I'm still saying that matchup is even, maybe 55-45 for Wario at this point.
Jiggly could even pose to be a counter but I'm just theory crafting here. She is floaty enough where MK isn't going to be comboing her, while she can combo him, not to mention how insanely early Rest can kill MK. Again I'm also excited to see the Marth matchup. Marth's ground game is going to constantly outspace MK, and Marth's aerial game while still being beaten out by MK can offer him more competition. Range is a key factor in the air, but MK has his jumps and shear speed going for him which gives him the edge. Marth's biggest hindrance will be his recovery, but if he keeps to the stage he should be able to have the advantage.
Again, theory crafting here.
