I have actually Ao + Hinata + Orochimaru and midnight blade, but I feel that is too weak in combos and power. Give me some advices and decent line-ups. Thank you so much and have fun. My ninjas:

I don't have any powerfull shinobi like Pain, Darui, etc... because I'm F2P user and I don't pay, and my luck is over in recruit. xdddd
