I think that Itachi's tools follow his soul. Yes Sasuke has bis eyes BUT Itachi used that sword against Nagato. It can't be owned y two different people.
Bottom line i dont think Sasuke has it be has that black flames sword and throwing discs.
I think experince and stamina will defeat Sasuke vs Tobirama or any of the Kage Edos.
I wonder how he will react when he finds out Minato is Naruto's Dad?
