yeah, BF i.e. let U tech grab combos. In general platform make pressure on his landing. But for me vs Falcon is important ceilings and stage dimension. In smashville is nothing and u are offstsge, considering also how much he travel with grab. And Falcon has some good option vs recovering Fox. In DH u can force him to approach with lasers, but couldn't on SV.
Btw. On the MU I suggest to abuse of trumps and nair mix to cover his poorly getup. Punish not sweet spotted upb with utilt bair, and try to steal stock with foxstool. But when u recovery, always sweet spot if is trying to edguard.
Utilt string is effective but need some%.
DI simply and always away from him on throw, after not to much combos will not be guaranteed.
His OOS option are risky or not so good (besides grab): press his shield much as u can.
Finally, is really easy combo/land uair on him.
