It doesn't get a boost from clones dying i tested that a lot. If you really want to get a really strong team that can boost orochimaru grab snake cloak kabuto, dps hidan. Your going to either get hidan back every 2 rounds and he will die boosting orochimaru or you c*e kabuto to boost when the units he revives come back and die again. Also with some combo chases you can get kabuto's mystery every round or every other round making it 10x more annoying. I'm sure others can come up with a better team though.
