totsuka sword,susanno and yata mirror :/ i'm going with itachi, althought i can see tobirama using
s/t to get into susanoo, and possibly attacking from there , then again, bringer of darkness can blind itachi, making amaterasu, susano, tsukyomi , all his doujutsu useless
tobiramaa doesss have tonss of experience fighting full blooded uchihas :/
also on the numerous occasion he met with the uchiha to fight, the two top senju would have to go against the two top senju, so i'm thinking he had experience fighting izuna or madara both with ms, fact is madara knew of edo tensei, which means tobirama had to have been using it in fights
don't think so, i think that was something special with hashirama
