not that simple but sure lolvs ROB just spam Tornado. His shield is weak!
dair doesnt work if they space. upB is better but still doesnt work if they do it right, and then you just get nadod' or naired when you land. best option is to run awayreplace actually in my last post with the word currently. Makes more sense probably. Even if they are though you can just up b or dair OoS to beat it.
platforms is bad. because then i just jump up. you are above me and i am in a great position to juggle you >_>Or simply get on some platforms or the ledge like you mentioned. Just get away from them, their jumps run out fairly soon before they have to refresh them.
pro tip : DO NOT BE ABOVE METAKNIGHT EVER.
