Anybody who knows about the cut-scene Sasori didn't use his own body or his performance of a thousand puppets nor did he use his irond sand, as were Konan had to use her paper angel mode. That fight was polished just to make konan look good like seriously they were in the middle of the desert they must be enough iron sand out there for the 3rd Kazekage puppets advantage on top of Obito given Konan intel about Sasori which he knew nothing about here.
