What lineup do you use

I find it pretty easy to win matches with my kakashi summer also if you get a specfic rank say Super Kage you will always keep that rank even how many times you lose and everytime you lose you get -1 point but if you have a winning streak you can get +1, +2, +3 sure it's a struggle when your matched with p2w or even just people with more initiative but it's isn't supposed to be easy and everyone will lose once in a while.
