Re: Tobirama Senju vs Tsunade, Kakashi and Gai
We have no idea what Tobirama's S/T is (I'm leaning towards some sort of dimensional pocket filled entirely with water) but assuming he can dodge Kamui with it? Seems unlikely, not least because Minato stated Kamui to be far superior to it. I'm aware it was Obito's Kamui, but they are more or less equal in potency, at least now that Kakashi has become more capable with it.

If there is a nearby water source Kakashi can nullify his techniques for a while, though Tobirama could easily outlast him in a pure ninjutsu battle.
Kakashi is also capable with Earth Walls, which posses the elemental advantage against water. Tobirama has shown himself capable of carving through Hiruzen's mud wall, so it may not make much of a difference.
Gai would eventually overwhelm him in taijutsu, and could end the match with a well-placed Hirudora.
Tsunade could heal and replenish the Eternal Rivals in terms of chakra, or take to the field herself.
