My intentions weren't about making this thread a Minato vs Madara thread, but on that topic:
Madara can make himself untouchable from Minato as long as Susano'o is up. Yet Minato is still one of the smartest thinkers in the show. Not to mention the fastest thinker. His reaction speed is supernatural compared to most. If Gaara and Oonoki found a way to make Madara vulnerable, Minato has a huge chance of doing the same.
And to Apple pie of doom, what attacks has Madara shown that could hit Minato. And for the record, the only attacks that seem to be able to hit him are either instant or above Minato's own level of raw speed, which no one in the entire show besides Juubito has accomplished. Minato's reaction time is almost instant, so the attack has to pretty much be instant to have any chance of hitting Minato.
That's why it seems like I ride Minato so much, because I can't possibly see anyone BESIDES JUUBITO(who for the record is a god shinobi) actually landing a killing blow to Minato. Kishi hasn't shown it, and his title in the 3rd war kind of stated it.
Let's actually go down the list of Madara's jutsu and see which one has a chance of putting Minato in a sticky situation.
