for the falcon thing, link really is supposed to beat falcon, you can just space him out forever and just use Bair and Nair to confirm kills and stuff for free, and he falls into Utilt strings nicely. overall i'd say use mac fairly sparingly and focus more on DDD/link in usage, since they have far less trouble with shiek and stuff, even though shiek is hard AF for link. main MU i'd "reccomend" mac in is fox. link can't beat fox unless the skill gap is insane. not sure what to say about DDD, main things i'd say for Falcon is to not panic roll/airdodge unless you want a knee of justice to your arse. and play extremely safe with all 3 characters.
