I was going to do a video on this later but i might as well do it now..

One of the standard ones would be iruka, Asuma, LM annd Sasuke.
Could also be Iruka Asuma, Hashirama, Any Main.

One that worked better than the iruka/asuma combo was Shira in front, Yamato (Breakthroughs would be nice), Earth Main... and maybe Lee Breakthroughs or Asuma/Iruka.

Another good combination is Wind Main and use the scaling to increase damage. Then use ninjas that buff wind and chases comboes.
