Currently my team with Edo Minato is Wind/Earth Main, Edo Minato, Iruka, and Gaara. I position them like this:

W/EM Edo Minato X

Iruka X X

Gaara X X

With Wind Main, a must use is Dance of Impetus to refresh Minatos mystery CD.

With Earth Main, I use him to provide shields for the team (kinda like a healer but with shields).
