Karin - Kakashi - *X
*X - MB - Hinata
*X - *X - *X
Seems pretty good on the surface.
I know I've heard that Sasuke over Kakashi is apparently better, but power wise / combo wise, I think this is.
Just uses a simple Chidori Blade Shadow, Beam of Light, Lightning Sword and Enhancement of Lightning Style Users.
I have a few ideas for people I can substitute in. Gaara can take Hinata's place, I'd obviously need to swap my Enhancement for Anbu Special Assault Tactics if that were to be the case. Sasuke is an option for over Kakashi. Kabuto is also useful for my previous build, so I'm keeping him around.
I'd considered using Sakura + Zabuza, but I'm not sure how well it'd work. I know Gaara, Zabuza, Karin used to work quite well when it comes to stalling the opponent.
Also, whilst I don't have Sai just yet, I've been told Kabuto, Kakashi, MB and Sai is really fun to use, considering you constantly have a field of clones. For the time being, I'm experimenting with Naruto, Kankuro, Shino and Chiyo for a similar effect.
Let me know if you guys have come up with anything else that's good. :)
