Awww did your jimmys get russled? I can see theres a bit of butt hurt in your post,
.black rods are basically chakra demodulators or receivers,they don't at all seal anything besides restrict chakra. Minatos chakra reserves are meaningless when all Minato needs to do is tag Sakura once and its over.Since he has knowledge,a rasengan to the head would end Sakura rendering 100 healings useless.Flying Thunder God goes hand in hand with Sensory types like Minato too. If you cant sense your marks it probably makes teleporting to them disgustingly difficult,the fact that you said she could knock them away gives him even more advantage here since he can teleport away from her ground punches,eventually he would be able to tag her. Only way Sakura is landing a hit on Minato is by a suprise attack like she did with Kaguya and Shin,though the latter both were distracted by Naruto and Sasuke so that can't be used as an excuse.
Its no wonder people here think you're such a troll and its irritating af. You barely have an argument worth negotiating with. Goodbye.
