I beat this 4* MInato Edo Tensei with Skill Trial easy with an outdated team in arena (Kurama/Minato Hokage/ Iruka with ST and FM), my opponent had more INI and even used Kakashi Susano'o and Itachi Edo Tensei. Too bad I deleted the picture. He is very overrated.

EDIT: He also had Edo Kages Barrier if I remember correctly...
