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.

Thank you for the suggestion but i dont have Kurma naruto or samui :( BP is there but i havent been able to beat him yet

it's really hard to give you a good reply, but if i have to say something you could do is to use kushina habanero, seems currently the only ninja that may let you be able to do something there.

That said i think you have to be happy he runs poison tai because means he doesn't run experimental ninjutsu (and so doesn't wipe you out with shark bomb followed by naruto mystery every round).

ehm, have you read what edo hashirama does?

Without initiative, you're pretty screwed. You'd have to run something that wont allow him to get his 20+ chases off. Super armor and dodge would help, but your main would always get the kurama focus unless you run EM with steel body or something.

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.

I do how power him by like 5k and have more init but the edo hashi healing is what kills me
