No. Wolf vs Mk is close to even. Wolf is heavy. Wolf has a projectile. His recovery isn't as linear/predictable as Fox/Falco. He has an Fsmash or Dacus out of aerial release on Mk. Mk is slow in the air and Wolf kinda ends destroys an Mk in the air.
Wolf is as good or better then Fox/Falco vs Mk.
If Mk does ONE Dsmash on Wolf's shield then that's a free 14%? (From Fsmash) or a Dsmash from Wolf, which kills.
Not to mention Wolf has shine, which gives him ability to land without eating Mk's Fsmash/Dsmash/GSL grounded because of it's invincibility frames. It keeps him safe.
In conclusion, Wolf has safe landing options, a projectile, he is heavy, his recovery is hard to gimp/not linear/he can scar through stages, and he is very mobile. He also has very good kill moves like Fair/Bair/Dsmash when Mk is around 110-130% (Range he dies). Wolf won't die till 180's.
