Ive been playing Rosa against my University scene for awhile, but the matchup I always seem to have trouble with is vs Sheik (no good Diddy mains, and im pretty good relatively speaking). I was looking to see how you guys go about punishing Sheik with and without customs? The moves im having trouble with are stuffing Sheik's Bouncing Fish especially. When Im in neutral, Ill exchange blows like normal, but the Sheik player uses a lot of single needles and plays passive. He spaces it close enough that if I go for the GP, he can punish, but he will also throw out a lot of single needles that stuff interrupt a lot of what I try. When I go for certain moves like d tilt or jab, he can react quickly enough and Bouncing Fish over Luma. I can shield him most of the time, but he will just bounce off or hit Luma and bounce off, and I cant seem to punish him for it, even though I know its coming. Is there something I should be doing to intercept or hit him when he bounces off? Should I be trying to challenge it with an Up Smash? Should I just go for the spot dodge? I could really use some pointers here since right now, its probably costing me games since he doesnt have to worry about my punish from it.
Outside of that, I have some difficulty punishing Sheik's Up B when used for offense and for ledge guarding. When used on offense, assuming hes using it carefully (which he does), I cant reliably punish its start up lag due to circumstances. That said, I would love to hear how you guys go about punishing Sheik's landing lag. Ive noticed that due to Rosa's lack of traction, shielding the hit and then going for a grab seems out of the question, and the push back disrupts/displaces Luma as well, meaning I cant go for a hard read F-smash in my experience. Lastly, I probably am underestimating Sheik's Up B hitbox size, but in trying to get better, I try to challenge it off stage with down air, but that doesnt work as well as Id like mainly due to Sheik's good arial mobility and recovery options. Thoughts on how to handle edge guarding Sheik?
Also, for reference, I did read the matchup thread, and I found it rather unhelpful in this regard, as there wasnt that much detailed matchup knowledge for Sheik. Thanks ahead of time, and I look forward to reading your responses! Ill take all the help I can get!
