She not.samehada can break big guy out of genjutsu and tayuya is strong but she cant put on genjutsu all seven swordsman the seven stated to be the strongest swordsman all seven had large amount of chackra and all were jounin level n one of them was and anbu ninja so dnt u think they can counter genjutsu..n we dnt even knw anything bout the swordsman except zabuza so some of them might knw how to get out of genjutsu.
Only part I cared about.
Kishi trolled most of these guys saying they were the strongest generation of swordsmen yet we see the basic uses of their swords and then nothing more of their individual abilities. In fact we don't even see a minor spectical of fighting without the swords. At least with Zabuza we found out his mastery of the Water Element, Anbu training which put him at a pretty high level of general shinobi knowledge and we can look at how Haku turned out to see the efforts of Zabuza's training reflected in him in some ways.
There's not much to go on elsewhere. I would've expected to see some more of Mangetsu especially since he mastered all seven blades but I guess not.
What I'm trying to say is, we use the seven swordsmen in a fight, at least use the guys we know of for sure; Kisame, Zabuza, Raiga, Chojuro, Suigetsu (if you wanna count him), Because these guys have a file stacked enough to actually make a vs. thread while the others don't even have a page of info to use unless you want to replace Raiga with Ringo and just say she can use all of his techniques even if he was filler and she was canon, I believe the gist of the idea with the Kiba blades would be the same as what we've seen.
And if it makes you feel better to not have people say Kisame would solo (which he probably wone if he used all his abilities) Restrict his use of Samehada in a way.
