Nope, I think you are a Minato hater, so stop your nonsense. Minato learned frog jutsus and some sealing jutsus from Jiraiya, despite he learned the forbidden once from Kushina during his lifetime. Minato did admit he learned Sage Mode, but he couldn't used it properly during a fight, so he avoided using it. He even managed to learn Sage Mode as when Naruto learned it, but the only thing that caused his chakra was because he could not maintain it for long.
You should really pay attention to the manga, instead of saying Minato got asspulls. Go and read the fight during Naruto vs Pain, then you know why.
And really? lol... How can someone take on Juubi Jinchurikis? Only them with Rikudo chakras alone can seal or completely defeat any Juubi Jinchurikis like Madara and Obito. Madara wanted to see Guy's 8th Gate power, that's all. He could have used Limbo and negged him anytime. Juubi Jinchurikis can only be beaten by extracting the Bijuus, but that's not possible when you are fighting someone like Madara alone, and yes this is a 1 vs 1 match.
I can still go on.
