If he's just throwing out moves to stop you from approaching,
maybe throw sausages at him? Also G&W's Dsmash has good
range in case he gets roll-happy. And Dash Attack is good
for punishing whiffed smashes when reasonably close enough.
And when people say Mac's air game is bad, it doesn't
mean he's bad at countering air attacks. You may have noticed
G&W's air-to-ground is somewhat lacking. Relying on it
won't get you far against most players, especially not Little Mac.
No offense @
BBC7
, but you have a bad habit of letting
bad losses of getting you extremely salty and losing judgement.
I have a lot more things I could say to help, but I'll just
finish by saying you probably fished too hard for grabs and
air attacks, things that you felt hard countered Mac, when
you could have been poking more safely with things like Ftilt,
Bair and Chef.
