You can try this:
Team1:
Kimimaro, Orchimaru, Tayuya and Kabuto. Kabuto's Human Experiment will raise kimimaro's and tayuya's stats every turn while providing some fodder with his clones. Orochi deals some serious damage and his resurrect can prove invaluable in ranked since it lasts long enough for it to happen a few times so you want him somewhere at the front along with Kimi. One downside is Tayu gets move order 3 or 4 so she might sleep ninjas that have already used their mysteries. But the main downside of this team is it has no good combo for the rounds Orochi is down.
Team2:
Guy, GNW kankuro, Kakashi, Tsunade. Guy provides a much needed passive to every team with his leech as well as boost the stats to everyone in this team(at least their standards). kankuro starts a combo every round he has his puppet out as well as put DoTs up. Tsunade provides some nice healing and sustain with the occasional lucky Chaos infliction. Kakashi is there simply to connect everyone.
Team3: Azure, Suigetsu, Tobi, Hinata. Azure's talents should be 2-2-3-2-2 with Illusion crow. Hinata should be in the far back in the middle row while the rest of your team is lined up with Tobi front, Main middle and Sui back either on top or bottom. Depending on where most teams opposite to you stand you go to the row they are not
Which team is up, middle or bottom is for you to decide after seeing how the others in your server place theirs.
I'm not sure if this team will work better than your current one but at least there's only 3 ninjas(Orochi, tsunade and Tobi) that would need additional work to catch up and they're all quite good so you can try it and see if you prefer it
