Stolen powers is special in danzou's case because he really did steal them and he spams the crap out of them. With an entire clan worth of sharingans to spam izanagi with there will not be many capable of touching danzou let alone beating him. I'd say only talented uchihas like madara and sasuke and the senju brothers. He would beat kcm naruto with izanagi spamming. Not to mention kotoamitsukami, if he has that available he can 1v1 anyone simply with that and not even need to fight.
Since Danzo has Senju dna he can pretty much spam KA. This is proved in the fact that he had it in the end of his fight against sasuke even when he used it on the kage summit. Also using KA against a perfect jin might work since you wont notice the effect of KA until its too late anyway.I doubt he would be able to even land a single hit on Naruto. Naruto is faster, stronger and has more power in general. At max Danzo is able to use Izanagi for 11 minutes. Kotoamitsukami can only be used once every decade, and its possible that it wouldn't work against a Jin as that would make the Bijuu take control over the host's body. A Perfect Jin cannot be affected by any normal Genjutsu, however we don't know how far that term stretches.

Its save to assume that he used it because his intend was to make mifune choose him as a leader and if he was still preparing the jutsu AFTER mifune has already choosen it would be pretty useless. Also by spam a meant he can use it every 1 - 2 hours or something like that.Proven fact? It wasn't directly proven that he preformed KA under the summit as he never said he did and its no other way to prove that he did. He may have prepared to use it and that is why his chakra network was acting up. Also if he could have spammed it then he would have used it on Sasuke and Obito but he said he was saving it for Obito.

No in Danzo's case, even if Mifune was leaning towards him he would still have used it. Danzo is the kind of person that will make sure it happens, rather than taking chances. So he would have used it regardless, however seeing how he comments that he planned on using it on Obito makes it rather obvious that he didn't use it on Mifune. That or he is indeed able to lower the waiting between uses. However, that really doesn't help him in battle as he can only battle for about 10 minutes. Also there is still no proof that Senju Power alters the way KA works.
I really dont get your logic. The first thing you said proves my argument. Also another proof is that danzo couldnt use KA in the beginning of his fight against sasuke and then near the end he was able to use it again.
I don't think he'll use KA in combat purposes,, and he has to wait a decade or so to activate it again..
