lol stats. It sounds like you've never tried to grab someone before.
Sure, you have to make reads sometimes, but you're not limited to their LANDING lag to punish them. DD, if they SH to try aerial/laser/whatever, you can grab them for it (or whatever).
She has some serious process work to go through to make anything happen against Fox/Falco/Wolf/Falcon, that's for sure. Her punish game on them is severely lacking from a flat stock without any decent damage on them already. Lots of development to be done before they become any less difficult to deal with. In the meantime, don't let them shoot lasers at you for free. You can do stuff, so do it.
Some others were here about an hour ago, and one of them asked the other "who do you wanna fight?" and the ZSS player said "not Fox, I'll fight him with Mario or Lucas, but not her, at least not until I'm way better with her"
That seemed to be directly in line with the majority on the Fox vs ZSS topic. haha
To what you can. DD, grab his face.
Dive-Kick knocks him down at 0% with a direct hit, that's always handy, and Down-B is often one of the best ways to not fully commit to anything, but still be threatening and mobile at the same time, both in the neutral game, but more importantly, on the offense in those 'can only commit to one thing' situations.
Otherwise, DD all day.
