My Lightning main is currently lv53 and the formation I am using is Midnight Blade (2*), Neji (3*), Guy (3*) and Kankuro (4*).
I should reach lv55 tomorrow, and this formation is kinda weak at the moment since it lacks the "Tankiness".

I was wondering if you guys could help me find the good formation(s) to stay on top of ranked.

My ninjas are :
Midnight Blade (2*)
Kankuro (4*)
Neji (3*)
Guy (3*)
Hinata (3*)
Ukon Sakon (2*)
Kimimaro (2*)
Karin (3*)
Kabuto (3*)
Gaara (3*)
Kakashi (3*)
Zabuza (4*)
Baki (3*)
Team 7 (2*)
Asuma (3*)
Others...


If you guys have a good idea for the main formation or even for the 3 full formations for ranked, please tell me :)
