keep 2 charge on hand whenever possible. if they don't pay attention to your charge, ram into her. If they start paying attention take advantage of them being jumpy and not using spike chaser.
watch their meter and form when you get in. With the neutral game heavily in their favor you don't want to ruin the chance you get each round by getting hit by a counter assault or super.
the special charge and blade super are nice here, but everything else is worse this time around. But they make a nice difference.
For nu, she hurts and almost always can lead a combo into her oki. This doesn't really make much difference. She gets less time off of it in CP and she doesn't have an instant overhead so it's not nearly as dumb. her ranged oki was strong in EX anyway. Overall doesn't seem to be able to convert to as consistently high damage, as in EX if she had 50 meter almost anything she ever hit with led to close to 5k.
For the most part though you just have to use basic movement options to win here, so there's not much to say. Slight favor to Nu or even.
