What are some good options for ledge guarding as Sheik? I am decently new and I am finding that this is an area that I really need work on.
To me, Sheik's edgeguarding splits into 2 categories, onstage and offstage edgeguards. Onstage would be something like needles to stop a Marth who's Side-b stalling or maybe a puff. You can also use different angles with the needles to hit different recoveries, which is especially good against characters like Fox/Falco. (This is why I think Sheik is amazing on Battlefield). Offstage would be something like running off of the level and going for deep edgeguards, which is really good against Fox/Falco because of the charge time on their Up-b. The most simple way to look at it is to just to know when to use certain moves. Each aerial has a really good different use. Nair is a great sex-kick with a large hitbox, Fair is a monster if you can accurately hit it, back air is really good from the ledge, and needles can be really versatile. Just practice against a multitude of characters until you can get a good feel for it.
