i think that playstyle is wrong...
personally, i combo whenever my opponent seems punishable by an abk
bair is pretty much the best neutral/spacing tool, you need to master it if you wanna play seriously
and... go HAM off stage, if you dont go ham offstage you won't win, this is where bayo excels... your combos are super inconsistent and most top characters already have 50-60 damage combos they can pull off dead-brain with just muscle memory... if the opponent has a great recovery (wolf, pichu, palutena, inkling, olimar, wario, etc) odds are you wont gimp them even with all the experience in the world.... (while mario, shulk, fire emblems, etc) are super killable
Most underrated gimping tools i see nobody ever use:
-upb: YES a single upb kills half the cast... just go off stage and upb them from below.... with your second upb and third jump (you need to master this too) you'll make it easy back on stage... the single upb's knockback is very similar to melee's fox shine
-falling held nair
-dair (you need to know how to recover from this or you're dead... if you can third jump consistently youre good to go)
-sideb to fair
