Dude use Tayuya and fire main with sleep talent.. + tobi for ignite and a extra ninja... you can win .. just make sure that extra ninja has nin as standart attack or taijutsu but in a position after the main earth enemy position.. also your main need to stay in front of earth main and if you have more initiative or 1ª before the main earth position, you can sleep him.. after it, just use Tayuya to interrupt skills of the others ninjas, and tobi to ignite...
