So our team looked like this

73 lvl, 27k power, lighting main 3*, danzo 3*, kimmimaro 3*, Guy 4*

talents: 1,3,4,1,3

summon: White Snake

73lvl, 24k power, earth main, kazekage gaara 3*, mabui 3*, sakura gnw 2*

summon: Giant Katsuyu

73lv, 26k power, water main, Ao 3*, Chojuro 3*, Suigetsu 4*

talents: 3,2,4,1,2

summon: Fukurokumaru

Our strategy:

1round used chojuro to clear it, 2nd round we used some skills to kill them fast enough, 3rd round we waited for minato strike, then healed and attacked all in on him to dont let him use his mystery twice in this round, in 4th round its just the end, ur doing everything to kill this son and father ^^

PS. PUT EARTH MAIN IN THE MIDDLE :)
