Agreed minato is a backstaber rogue "You can not see or touch him"I agree. His battle with A could be a hint that he has wind element. Only wind is stronger than lighting. Just ask this, why would someone considered a shrewd person/a genius attempted to stab A using a kunai if he knows that he can't hurt him because of the lightning shroud? It doesn't make sense, right? Purely common sense. Minato would mop the floor with the 3rd rai.
