I saw 2 Ideas that can work. You need to be competitive in BP for it to work. The first is a combination of Samui, Ay the 4th, normal Tobirama and Earth Main. Stacking Initiative on Samui and Damage on Ay the 4th could allow you to nuke Water Main/Edo Hashi. The other team would be Fire Main, KMC Naruto, Konan and Iruka. You need a bit of luck here. Edo Hashis case can't hit your KMC Naruto.
