Firstly, FTG cannot be traced by sharingan. Its teleportation. Now, even if we assume he can, sharingan doesn't increase his reflexes, he could track A's movements, but not counter them. Remember? Amaterasu doesn't even fit into this, Raikage dodged it at point blank range, Minato will dodge it asleep. Tsukuyomi, or other sharingan genjutsus? Minato's a hokage, and would know better than to look directly at an Uchiha with MS, not to mention EMS, the guy was a freaking hokage. Another important factor about Minato your forgetting is that he was never touched in a battle before, and that he had every jutsu required for the situations he find himself in. Its likely he has more techniques than just Rasengan and FTG. the guy was a freaking hokage, and a genius said to have made many original jutsus, i.e, there are probably more original techniques for him to use.
There's also the quality vs quantity aspect, if you're not ready to believe that he could pull out far more jutsu than he's shown. (Since unlike Sasuke, he has enough sense to give whats needed, and think rationally, infact, he uses exactly whats needed and nothing more or nothing less. A man who does nothing without a reason, even jutsus.). None of Sasuke's attack's can hit him, and he can't keep Susanoo forever, even with EMS.
This is all, not counting Minato's new KCM or BM. With it, its overkill, Sasuke will shit on his pants.
