>>21538341http://imgur.com/a/bNVHNSuicune, Cresselia, and Cofagrigus do a nice job. Cofagrigus might be the best option, since it loses its best move after the first blow, and you can fire off a Pain Split blindly, or get off Trick Room or something. If M-Sal has already DD'd, I think only Rotom-W can come in on it.
(M-)Slowbro goes without saying, so I didn't include it.
