I played a guy not too long ago who used a SubSalac NP Mismagius.  I don't know the specifics of his set, but it seems like a very good set in theory.  It's immune to Fake Out/Vacuum Wave, and Sub lets it play around Sucker Punch users.  Also, thanks to its 105 base Speed, it'll outspeed most Scarfers after Salac.  Ice Shard and Aqua Jet are the only two priority moves that it really needs to worry about, but the first only sees play on Donphan and the second on Azumarill, for the most part, and neither will enjoy boosted Shadow Balls if they switch in too early.
For those with Honchkrow problems, I suggest using a WoW/Reflect Rotom.  Since most Honchkrow aren't using Night Slash anymore, it's pretty much free to switch in at any time and set up a wall or spread status.  I've been using a Dual Screen/WoW/TBolt Rotom on my current team and it's been amazing.
