Already try this formation i can clear it once after lot of tries.. Need to add some power, at wave 4 my strategy is kill Hidan at round 2 before he kill us who have tag, so instead sacrifice Kimimaro and Neji, we kill Hidan as fast as we can with full formation (its faster and better point)

yes it works good in team but if a lot people wanna do it solo animal is a target !!
