Maybe provide the ninjas you have so you can help people making your lineups for you?

OK- darui isn't meta anymore (you're about 2-3 years late) but one of the best lineups is with Ay 4th Kage when he is 4* breakthough.

I highly doubt you have Ay 4th kage at 4* and fully skill breakthrough since guessing you're on a 2 month server.
