@UltimaDude How does it contradict the Manga?

@AsianReaper All I know of is that it's said in the Manga "A Sharingan that can activate Susanoo is a rarity", it's not saying A Mangekyo Sharingan that can activate Susanoo is a rarity. I don't see Tobi even implying it.

MS was said to only activate in a handful of users. In the anime only(I think) it was only shown that MS users were somewhat abundant over Izanagi usage (Itachi anecdote when explaining it to Sasuke) but there's no way to argue that the ones fighting were the only ones which posses MS plus Izanagi doesn't need MS.

As I mentioned before, I think OP should have clarified its usage in the debate but to me it doesn't make much of a difference.
