I've been doing 4D to dodge Excalibur, the tough part is to punish her. So the trick is to hit her BEFORE she touches the ground? That'll help. Now to deal with Kamui's insane range.
You have a short window of opportunity to hit her with just about anything after the move whiffs. If you miss it, a throw still works.And Kamui's range isn't that good if you compare to Nazuna or Scharlachrot
Thankfully, none of my friends main Nazuna or Scharlachrot (I've raged enough to LV8 Boss Scharlachrot anyways)What always gets me with Kamui is getting ounished after a tiny mistake with a far (Like almost mid-screen far) 5B, 5C, HCF+AB.
