Current team that I use for Survival Trial is :
Main - Guy - Clone
X - X - X
Kabuto - Kakashi - Clone
Summon is Deer ; Abilities are 'Lightning Sword' , 'Chidori Blade Shadow' , Enhancement , Clone Combination Tactics, and standard is 'Lightning Assassination Sword'. This team mostly dishes out a guaranteed 12+ combo even with a standard attack. Hope my suggestion helped. :loveliness:
