Hey,

She is not really the best ninja to be considered as position one, but here are few ideas :

Itachi is there to trigger another sleep, since it'll be easier then to use Fuu's Aoe mystery. Additionally, fire main with the illusion passive works as well. Gakido can be changed with any other supporting ninja as well, such as Sai suit, any other healer or reflecting ninja, etc. The good thing with this team is, that once you put them all under sleep, you will most likely be able to trigger the Aoe of Fuu at some point. Try the different combinations out and see which combination is most fun for you.

Hope that helps ~
