I think nullification would be a good semblance, but like most abilities it will be most useful if your opponent doesn't know about. So if you are an assassin, get close to your unsuspecting victim and remove his Aura just when your are delievering the finisching blow, it will be quite effective.

Another interesting aspect is the interaction with semblance. If someones figthing style relies or is based completely on semblence, they will have a really hard time. Just like Ruby had when she lost Cresent Rose. At least one OC of mine would be fucked.

But even if we don't get a character with such an ability, I'm still pretty sure that an aura suppression technology exists in Remnant, at least in prisons.
