It's more Kakashi's intelligence than the sharingan at this point, but without one, the other is irrelevant at this point.Thanks to the Sharingan Kakashi seem to be a good counter, but now Tobi seems to also figure out what Kakashi did so now we will see if he falls for the same trick. With one Rasengan from Minato, Tobi was weaken now he ate Naruto rasengan up. I wonder what will happen next week
If the juubi isn't ready soon, Tobi's not going to have much of a choice. He's shown no ability to fight people in taijutsu or ninjutsu battles...much less 4 ninja who range from mid-kage to demi-god tier.
Not to mention, K11 should be showing up soon. While yeah, they're fodder in the grand scheme of things, that's still 11 extra people attacking him. How can he deal with that? Intangibility isn't going to save him now.
He can't leave the battlefield, otherwise that leaves the Gedo open to being attacked and killed.
Tobi's in a tiiiiiiiiiiiiiiiiiiiight spot.
But no worries, juubi should break out soon.
