Like Qolem said, post your ninjas. To be completely honest with you, if you don't have some type of rare, you're going to have a lot of trouble keeping up.

I'm f2p for the most part, and I cling to my Onoki like a lifeline. Every team I make includes him. Use your rares wisely.

Assuming that you don't have anything, the only team that I think would compare is the classic Root of Warrior team. Sasuke, Kimmimaro, Jugo, Lightning. It's not ideal, but it works
