How do I consistently gimp Diddy when recovering, especially when he uses the jetpack and recovering high? My edgeguarding in general is pretty weak, but while I'm always told Diddy's recovery sucks I can rarely seem to stop him from coming back onstage. My best bet is usually just hitting him out of SideB with Mega Man's Bair (I also play a lot of Greninja and a little bit of Pit & Rosalina on the side sometimes, and I can't gimp him much with any of them), if I can even catch up to him and hit him at all that is. Some Diddy's charge the jetpack and fly right over my head and I dunno what to do about it.
On a side note, do you also have any advice for what to do when he makes a Banana? The banana is the most annoying thing about fighting him imo, shielding doesn't seem to be too safe on option when he can command grab, and somehow I almost always end up eating a Banana > Fsmash combo and get killed. I've tried grabbing his banana and using it against him, but it's only been effective for me sometimes.
