sasori/deidera>sanin
kisame/itach>sanin
pain/konan>sanin
kakuzu/hidan<sanin
deidera/tobi>sanin
i think that is all the combo's they used...
sasori/deidera, if they actually fight as a team and not 1v2 ppl far away from each other can actually wreck most cominations of shinobi in the naruto universe
kisame/itachi, same explaination as sasori/deidera combo, and just to emphesize how powerful sasori/deidera would be together i believe they can wreck this team, but the sanin wont be able to keep up with kisame/itachi's rediculous attacks
pain/konan, using the six paths of pain can actually wreck the sanin pretty easily
tobi/deidera, im more guessing that sanin would lose to these two based on the fact tobi is suppose to be all powerfull, give this one either way actually
kakuzu/hidan, the sanin would rape these two quite quickly
these prediction are based on oro not being able to use impure world resurection
