Counter the Suiton with a simple Katon
Except Suiton beats Katon. Don't bring physics into this, in Naruto water >>> fire.
And lets not forget, that much like he did against Deidara's explosives, Sasuke can easily counter this by simply evading it with his Shunshin.
Tobirama is faster than Sasuke, so good luck with that.
Sasuke's Raiton would travel throught Tobirama's Suiton and ultimately paralyze Tobirama.
No, the lightning would electrocute the water, not Tobirama.
Lightning does not beat water, it simply electrocutes it. Nowhere does a raiton pierce through a suiton and hit the user.
Sasuke will use his Shunshin in order to evade it.
Countered above.
First, to erase the danger of Tobirama ever getting near to him, Sasuke can summon both Aoda and his Taka to the battlefield
Never saw someone with 2 contracts at the same time. Sasuke probably ditched the Hawk one.
B] With the formulas (markings) gone, Tobirama will be unable to teleport to anywhere now.
He can mark his edo or use clones.
Or he can simply mark more places.
C] Genjutsu is one of the ways Sasuke could use to bypass the Hiraishin. Considering that Tobirama already looked into the eyes of an Uchiha that is supposed to be superior to Sasuke multiple times, I see no reason as to why he won't look into Sasuke's eyes.
Genjutsu is not instant. The second Sasuke starts gathering chakra in his eye, Tobirama can either FTG away, close his eyes or simply bunshin feint it.
Sasuke's Susano'O was teleported with him. [1] Why? Because the user and it's Susano'O are connected and that's exactly why the Susano'O got teleported along with Sasuke as well. Hiraishin teleports things that are connected to it's are connected to it's target.
Susanoo wasn't teleported, it vanished.
It has been shown before that Susanoo and its user can be separated.
Not that it matters because even if Tobirama teleports his Susano'O, a new one can be created.
Not only does that take time, it also strains Sasuke.
His so called great reaction feat of him reacting to Obito's attack doesn't mean absolutely anything since that Obito wasn't actually intelligent and as fast as the real Obito.
Bullshit.
You don't have to be Einstein to run fast. Tobirama reacted to the fastest character in the manga, his reflexes are top tier.
considering that even an ill Itachi managed to create an Amaterasu that was a lot bigger than a human sized target.
Seeing as how Sasuke ran out of chakra much faster than Itachi, that doesn't mean much. Itachi has hilariously superior chakra control. ( that, or he has more chakra ).
