in every 60 you get one rare but because you say that you get killer bee two times that mean 120 and darui 3 times without 20 from event mean 180 and with that 120 from killer 300 and you have mei thar 60 and onoki another 60 and mufine 60 and gaara ( 5 kazekage ) 60 and danzo 60 and chojuro 60 . so 60 x 6 = 360+ 300 = 660 and you will get the super rare in 800~1200 so another 300 and maybe you get your super rare , and good luck :D
