i'd be careful about using EX tackle. i used to do it a lot (when people weren't used to seeing vice), until i realized how much startup it has. sure it has a lot of invincible frames, but unless the opponent high jumps at you, you're not going to get clean hits off of it. you'll notice that it has a whole lot of startup frames. though invincible during that time, it's practically blockable on reaction. like i mentioned though, it's good against high jumps, but probably not hops. it also costs 1 meter for EX tackle, so the universal GCCD/GCR are probably safer to use even though you don't get combo opportunities like you would with the tackle.
like Kane mentioned, her s.A is great against hops and her far s.D (the leg swing, not the knee which is close s.D) is great against almost any other type of jump-in. if you predict a high jump, a j.B air-to-air works pretty well into EX arm when you land.
also, like Kane suggested, command throw is your friend when it comes to punishing moves you normally feel like you couldn't punish on block.
as a last resort, if you have the meter (and want to be a dick lol), you can use her neomax to punish jumps, whiffs, stagger pressure, or basically anytime the opponent hits a button. it does a good deal of damage for relatively no effort. keep in mind that you probably won't have meter after this option lol
