People jump into Madara's bandwagon after seeing him do powerful jutsu's..wow..the problem is how is he going to hit Minato? If you analyze it properly and do some research, teleportation techniques uses Yin-Yang release. This is the sixth nature affinity and having this affinity means that he had KKG.
I personally think and I can prove that his nature type is YIN, YANG, YIN-YANG. YIN-YANG forms by moulding YIN and YANG, thus it makes him a KKG user. Only a KKG user can mould 2 nature types. DO you think that Minato does not have powerful jutsus? Rasengan and FTG are his signature jutsus but not his only jutsu.
How about earth element? I think he also has it because by simply touching the ground with his index finger, he could detect the presence and number of enemy shinobi. He needed the ground to do the jutsu..ground=earth.
He may also be a wind user..Naruto uses wind. It's 50/50 because Kushina may also be a wind user but his fight with A shows that he is trying to stab A with a kunai even though he knows A is using lightning shroud. Only wind is strong against lightning.
Now, if he does possess this nature types, do you think he doesn't have powerful jutsus that can harm Madara? Madara has no answer for his S/T techniques while Minato has space time barrier to warp attacks..Madara is a show-off type of ninja. He wants to display his powerful jutsus right away. Against Minato, it will not work and the moment Minato sees his jutsus, he can deduce it's basic mechanics and take advantage of it's weakness.
