He shields and boosts nin/tai attacks for all ninjas with the curse tag so he would work well with a full curse tag team such as Sasuke, Kabuto, Kidomaru, etc.

I believe his mystery conjures a shield that has the ability to interrupt a skill, and if it gets destroyed before it's able to interrupt anything, it causes tai dmg + knockdown to the team that destroyed it.

All in all, I believe he is used as a tank.

Well, that's a shame. I just went by what the description entailed.

I guess he can be pretty useful as a support for a tank team with Kimi and maybe Kido.
