How to fight icies as zss?
Space everything, **** Nana once you get her in the air. Get her offstage and spike her.
Don't use grounded sideB if they are/can get within the range of the first hitbox by the time it comes out. Don't use shorthop sideB, they can run under and grab.
If you ever land a grab (obviously be careful with grab) then bthrow/fthrow.
Wear down their shield with bair, dtilt, sideB, dsmash, etc. All of these should be safe on shield if spaced properly. Keep harassing the shield til it gets poked and you separate them, then destroy Nana with your everything cause Nana's dumb.
When Nana's offstage and trying to recover, she usually spams ice blocks. Learn the angle for this, and avoid them. If she's offstage and up high, approach her facing away from her. That way you can bair, or (if her ice blocks are preventing you from getting right in front of her) use the back hitbox of nair. Or upB spike>tether edgehog.
So I'm working on the Diddy dsmash banana lock. I have everything working except for the instant dthrow toss (last dthrow before the landing). The banana bounces back up as planned but Diddy falls behind me. So, it looks like I have to be closer behind him vertically once I dthrow so he falls in front of me, right?
Just wondering if anyone has had this issue and what helped you to correct yourself.
It doesn't necessarily have to be an instant dthrow toss. I hope you're not trying to ADCIT (air dodge-cancelled item toss), cause that's not necessary. Z-catch it (without airdodging) then move with the control stick and do the downward toss with the C-stick.
When you footstool, don't throw the banana downward
immediately, wait for a bit.
If the 2nd banana hit is sending Diddy backwards, maybe you're not fastfalling? Or not doing it soon enough?
If you still can't get him to stop going behind you, it's okay. Just turn around and dsmash, you can still infinite that way.
