4 me: Lars
Supp#1:Taka Sasuke-balance type( so when i chakra load my shurikens, Sasuke and Lars spam with shurikens b/c they both have a high amount of shuriken icharges )
Supp#2:Sage Naruto- Attack type
I would say Naruto Sage-Mode as user-character, Negi in Attack mode, and Sasuke in Attack Mode.
Naruto is good at using Rasengan Barrage on close range when the enemy is not looking.
Negi is good when the enemy is right next to you.
And Sasuke is good at throwing long-rang Fire-Ball Jutsus.
I'd normally use any form of Sasuke.
Backup:
Neji for his rotation or Hinata. If experienced enough you can use the short time your opponent is immobilized to use your ultimate before they are sent flying.
And...... Any balanced type. To get out of sticky situations.
