Sorry if i say this but... Who deals damage in that team?

Every decent kisame samehada team and every decent kushina habanero team sees at you as free food, to not talk about teams involving kurama naruto or itachi susano'o + madara or edo hiruzen. Yes, works fine against minato kurenai or shisui itachi anbu root teams and you have 50% to beat kushimaru meta, but... Imho you are lucky in your matching system.

The reason why you are able to beat kurama roshi bee is because they place kurama in the middle line and roshi in top line but after they lost once against you and they meet you again they just put kurama in bottom line.

Since the number of good ninjas is limited every team was tested before in china, so every team is copied.

That said i like what tiami does in the sense of trying to not use a commonly used team since is what i try to do too.

Yesterday i was in arena with a guy that asked me what was the purpose of my distribution of the ninjas on the field. The fun fact is that he was a whale running the only team that could beat the team i was running with 90%+ chance even by not owning initiative and is fun because he did not even know that i had won 33 straight battles before i faced him, so, maybe, meant the distribution was fine and was just him that had the luck to run that specific lineup against me...
