there isnt anything "Special" about kabuto aside from the fact that he can heal. When you want to build a team "around" someone. They should have a very useful skill.

You might want to try to build around Kabuto's Poison damage, or Shikamaru's immobile. ETC. something very useful.

If you get sai however, a good team would be Kakashi, Sai, Kabuto + ninja that can create knockdown.
