no, that does not works for me.
i thought u were wif vist, he can tell u about this match ups, but anyways
i play luigi, thinking about not getting hit, luigi is a deffensive character. 1st, never sh aerial sheik, u can try wif spacies, to see if u get a hit, a nair or something, but never do that on sheik. 2nd, do not chase sheik, space everything ur gonna do on her, cause, if the game would be perfect, luigi would not do damage on sheik if he would chase her. just dodge needles till she follows u up. trying doing this on sheiks. every time she fairs, dash, or runs to grab u, roll. there's gonna be certain times, where u would just jump, and punish her first (this would be in the moment, you will already read her, and ull sh, and dair her face, even down b works well in this situation cancelling both attacks and dsmashing immediately) . when she is on floor, first thing you gotta think of, is grab. CC isnt such a good idea, cause most of sheiks, go for the grab and even when they fair, u would not have the time to grab if they dont miss. u wont. try techchase her with dsmash, nairs, or even fairs, but grabs would be your best friend. bairs works pretty fking well when edgeguarding. and dairing at 60%< works fking good. when you grab in more than 80&%, and you are near the edge facing away the platform, try fthrowing her fast so they dont di, there, you can edguard, or waif for her to land and upB. if they land in a platform, fairing in the other side of her body so u send her towards your back, or dairing em, its good.
never follow her in the air, in anycase, you are loocking for a hit to get em, uair and bair forks well, fair if she is near, or FFing. but make it quick. luigi has no adventage on this matchup, none. so u gotta think to win. a lot.
jab her a lot when she is not CC. sometimes, even 6 jabs in a row would make her fell down and hit all of em. when ur coming, and they are sielding, always grab, and uthrow fast to combo at low %. if not, what i said above.
Falco: same history with the roll, roll every time he's getting near. but try getting a lot of uthrows. i practice PSing a lot, and that works pretty fine on me, i try to PH when falco shoots me the last laser to get over me. surprising fairs when they are getting closer works well. and fairs when u make pressure. making long wavedashes between they lasers despairs em. cause luigi's long wavedash works good.
other way to get em, is wait for em to come close, WL on the above platform quick, ff and bair. try playing wif jabs when they are near the edge, playing wif jabs and one fair works. but always one well spaced fair, try not gettinr grab. if falco grabs u and bthrows u, u are risking yourself to get a dair in the face. i edgeguard spacies with the tilts , bairs, fairs, and dairs. should. and when u just wanna pi on em, go after them in the air when they are using the up b, and fking side b em in the face, ull get a missfire sometime lol.
try ftilt em evetime after getting a well spaced bair, ull hit em/shieldstun them more time
