This match is pretty much a RPS (rock paper scissors) match in my opinion. You jump around blocking in the air all day to make nu have to guess between forward or up sword while you wait for an opening to dash in. I find being patient against a good nu can lead to problems. I mean one that makes use of her command dash to 50/50 crossup with grab/poke mixup as well as long ass strings instead of hurr durr sword spam 'mixup'. Nu doesnt have any reversals so once you get in on her run all the mixups you can because shes dieing in 2 combos so gets those hits in. also if nu is in the air and you're within her sword range, 6c > her.
