Considering Kamui and Tobi's Mangekyo are connected, I'm gonna go with the idea that either A) Tobi took Obito's eye and did the Mangekyo process which gave it to Kakashi having Obito's other eye, or B) Tobi is Obito so the logic in the series died before it even started.

But, meh. I'm not much of a fan of Amaterasu (It doesn't do any of the things it should do and as such utterly fails at being the "ultimate fire release technique") or Susanoo (Because the Uchiha's needed something else to be completely OP).
