sorry if this a bit out of topic, but I need help in order to defeat tsunade at minato/speed UT,

my initiative are higher than tsunade, thus my ninja always move first, but i can't manage to kill her, sometimes she manage to heal even if I keep burning her, or immobilize her with danzo chase, I hit only for a few hundreds but she heal for 5-6k, I manage a couple times to stay at full health till round 10, and she have more or less 60% health point left, but ofc i'm the one losing,
any tips in general on how to pass this? after the patch I still beat raikage and mei UT till limit in auto, but I can't pass this, even if I playing on it

any help and tips are appreciated, Thanks!
