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.

if the guy owns edo hashirama there's no way the other guy, that don't even own naruto kurama, may have higher initiative than him. We are talking about somebody that was able to use 3000 seal scrolls in gnw treasure, means is a heavy whale with 180k+ power at least.

P.S. i'm pretty sure he mistook edo tobirama with edo hashirama, if he is talking about edo tobirama then there's something he can do, but with edo hashirama no.
