Don't know what MS means, but I can't see 6th Gate being it, so they win. Air Palms and Rotation disperse Hidden mist for his allies if she uses it, acidic mist is useless in open terrain, Lava and Suiton is countered via Rotation. Lee blitzes any of them with 6th Gate, Shikamaru's shadow possession and Neji's air palms allow him to achieve that with utmost ease when Kisame couldn't dodge the latter and the former has shown to use his high levels of intelligence to almost always capture his opponent with his shadow possession. Mid diff.
Definitely win. Suigetsu is immune to Mei's Suiton, Karin's chains binds either of the two (assuming she gets them), CM2 Sasuke can possibly blitz, Jugo's chakra canons cause heavy problems for Mei's Hidden mist. Manda shits as well. Both are also prone to Sasuke's genjutsu.
Sasori and Konan go air-borne, and proceed to win easily. IS forces two antidotes, at that point they can no longer be touched by his IS, or it's an insta loss. Konans paper bombs followed by subtle IS ends.
I'd say he's a bad match-up for someone like Mei. Unless he can reach SM, he won't win, and I have doubts over him being able to buy si much time.
Round 5:
He eats them for breakfast.
Don't need to say much, he low diffs.
Once again, low diff.
Only close fight. If he gets his Hydra he spanks, if not then it can go either way depending on how he deals with Mei's lava and close range acid. Could go either way, but I see Oro eventually decapitating with Kusanagi sword, assuming it wasn't sealed.
