Here u got some skills to use and summons. Depends which formation you will use later. But you could use Earth Style Stone Fist Jutsu, instead of the second mistery. Also you can add Orochimaru (sannin) if you have it or traitor or nins that can revive at the second turn. Sometimes with Earth combos doesn't perfom so well, so you have to think FAST specially if you have fire mains in front of you.
