Agreed will all other advice, im playing MB till lvl 75. From what i see, lvl 55-70 just use Sasuke, Kimi, and Jugo if u have. u can replace it with tobi. lvl 70 change kimi with Oro sannin (its free from elite instance 70). And if u can save coupons till 1,8k u can get Iruka 3* from key event. Done, save all ure seals and wait for kage treasure
