I think that Kabuto is an extremely great ninja teamed up with Kimimaro. Azure Fang is also another great option since she has healing tips, healing jutsu, advanced healing jutsu, and water trumpet jutsu. You c*so use Great ninja war Hinata or regular Hinata for acupuncture and defense. If you are advance, Kimimaro and Kabuto is still a great option with Cursed Hidan and Lightning main. Kabuto with a tank-defense ninja a great to go combo as he helps that ninja gain resisteance and defense. It doesnt matter if your Kimimaro is 2 or 3 stars or higher. Tsunade can be a replacement for Kabuto since she deals more damage and can cause chaos. A heavy healing team can include him because he can heal 2 ninjas while his passive activates so that they can receive a good healing with that healing tips. A heavy healing team has to consist of water main with healing tips, ninjas who can heal others, 1 ninja that is a tank-defense , and has combos that fit together and deals an ok amount of damage.
