Truth be told, you cant have two Vanguard or Vanguard and Assault Oriented Zanpakuto, so get Jizo in case you need to change up your formation a bit to beat certain pvp oriented players, like me in some cases. no matter if your sebonzakura is on steroids or hyorinmaru you cant ever beat a control based formation with jizo except you cant KO or shut them down 1st. or your vanguard has so much dodge that they cant hit to furry.
