Dealing with floaties in PAL?

[GHOST4700]

because Sheik has lost her incredible down throw in PAL what does she do against floaties most specifically Samus, Peach and Marth to win the matchup. Because once I get a grab I have no idea what to do because I feel like she can't combo them...

Rely on other things than grab.
But when you do get a grab in, Dthrow emediatly with no pummel and see if they are awake and DI away.
If you catch them DI'ing in for example, you can follow up.
If they DI away every time then try for an Upthrow.
Yes it's terrible but I find Upthrow to be the better option. Watch them burn their DJ as you empty jump at them. Then Bair them as they come down.
Other than that you can charge needles for free after the Upthrow.
