Wolf and Marth go even.
They are both just great characters and they both put up a good fight in this match-up.
Wolf's blaster is good, but pretty easy to get past actually, but it's still a solid camping tool. Thing about it is that it's easy to perfectshield and it's somewhat slow.
Honestly most Marth's don't know how to deal with projectile camping but in the match-up really isn't in wolf's favor.
I mean think about it. Wolf has some good options that is true, but overall Marth has a more solid move set and he has the tools to win in close range. Marth has his up b which is invincible for the first 5 frames, his Dancing Blade which hits on frame 4 and the combo does decent damage, his d-tilt that he can cancel and set-ups up for follow up attacks, and of course Marth has his fair which is also tough for Wolf to deal with. If Marth camps in Wolf's face just outside his f-tilt range then Wolf has a harder time re-taking control of the match.
But it's not like Wolf doesn't have close range options. He has his shine and we all know how beastly the shine is, he has his great jab combo, his great f-tilt, his f-smash, his grabs are better overall so he can fall back on those and his good d-smash.
The main thing to remember is that Marth can gimp Wolf's recovery pretty badly and it isn't too difficult to do and also that Marth outranges Wolf in close combat which also makes it harder. Wolf's main strengths are his camping, his shine and his really good smashes that can be somewhat difficult to punish, and his jab combo as well as his f-tilt give him something to rely on.
Overall I think Marth's are losing to Wolf's alot because..well..let's be real. Wolf is eas yto play and he r@pes. He is just awesome. He hits hard and fast and his moves are crazy good, especially his smashes, his f-tilt and his lasers. I mean his gun hits on the way out and combos into the laser shot. His f-smash launches him forward and hits twice. Wolf fights really unorthodox and is extremely deadly and he isn't hard to use, while alot of Marth players try to play Marth the same as in Melee and fail horribly and have no idea how to deal with camping at all.
But when you actually look at all the tools the characters possess you realize that Marth nor Wolf really r@pe the other. I think they go head to head in a 50/50 match.
