Well, these are the only ninjas I have currently for coming under the conditions given.

Though I thought that this team would not deal much damage it actually did which surprised me a little.

So the main damage dealer is my LM with lightning armor, breeze assassination sword, lightning enhancement, and bloodthirsty demon for those double standard each round.

Ramen naruto buff my LM with +30% crit, an extra standard (total of 3 atk per round), and some damage through chases in which one of em causes ignition.

Sai mystery is super useful as it can reset my LM lightning armor which results in a lot more damage and not to mention the immobile from his standard is also useful.

Tenten mystery can be spammed if we have a minimum of 50 chakras to reach this amount sai helps as he can fill 20 chakras each round and the chases for some extra damage.

All this together I was easily able to beat Fukuromaru and grab the maximum reward.
