So basically now Tsukishima has "seen" Byakuya's sword techniques "many times." Does this apply to just the techniques of Senbonzakura's Shikai or EVERYTHING? Even so having knowledge of something doesn't necessarily mean you'll be able to defend against it. Besides Byakuya still has an extensive arsenal of Kido Spells that I doubt Tsukishima "knows" about so Tsukishima won't have the advantage for long. Plus Tsukishima made the universal blunder of telling more about his abilities so now Byakuya can find a weakness in Book Of The End (hopefully).
