Pretty much most of the cast can recover, you just have to provide a little extra nudge to kill them. Like ness you just have to pretty much go offstage and Bair him far enough so he cannot recover. People like Lucario/shiek you have to edgehog to get them onstage and then punish the ending lag of the UpB. Some are too risky to attempt like MK, so you just have to work keeping him offstage. ICs are not even worth mentioning.
