What about the Darbys' soul collecting stands? Sure it would be stupid if Kars actually had a reason to play them, but if his soul gets sucked out... isn't that it?
Interesting question, but the problem is a victim of D'arby must admit true defeat within their own mind. I bet Kars could never see himself as being defeated, therefore would be totally immune to either D'arby's Stand.
