Of course Heal Bell is so rare on her that it doesn't even register on the move set statistics so I don't know whats going on with her.
Mismagius has a few niches that the other ghosts don't bost. It's immune to Spikes and Toxic Spikes, while only taking normal damage from stealth rock. If you look at all the other ghosts in UU, all of them are weak to every form of hazard, Froslass and Chandelure are actually weak to Stealth Rock. Mismagius also has the highest speed of the ghosts save for Froslass, although with better defenses and typing. This would make Mismagius the most consistant Spinblocker with the ability to Taunt. Might not seem like much, but this would protect it from stuff like Toxic. Lastly, Mismagius can also set up Calm Mind pretty consistantly. Chandelure hypothetically could do this better, but since everybody's too busy using Specs, Scarf, and SubSplit Chandelure instead, Mismagius is used for this point. Mismagius also has Perish Song, which although it's rare, is a cool move to use on stall teams.
Now don't get my post wrong, I'm not saying Mismagius is the best ghost ever, or anything silly like that. I'm merely pointing out the fact that is has way more uses than people give it credit for, thus explaining why people still use it on the ladder. I would agree that 90% of the time, Chandelure, Sableye, and Cofagrigus would be better spinblockers. But Mismagius still has its few niches that make it useful.
