I felt like writing tonight/this morning. (Whichever one keeps ya sane)
Why OU?:
Misdreavus is one of the ‘gems in the rough’ of 5th Gen. With Eviolite & Max Defense, she reaches a very respectable 324/360/309 defensive spread, (beat that, Jellicent) which actually makes her a great deal bulkier than ye olde Rotom-A as a Levitating Ghost. Levitate not only gives her (T-)Spikes immunity, but it lets her freely switch-in on Ground-types like Landorus. Add that to her Base 85 Speed (Rotom-A is Base 86 for reference) letting her out-pace & Will-O-Wisp Tyranitar, and she has more than enough perks over her younger brother Dusclops and even Jellicent since access to RestTalk makes Toxic & other status a non-factor and trolls Gliscor to no end.
She's also adorable.
QC Approvals:
Misdreavus
[Overview]
<p>Until generation 4, mischievous Misdreavus has always been able to carve a unique niche for herself in OU as a stall breaking Perish Song trapper. However, as soon as she obtained her evolution, Mismagius, Misdreavus fell far into obscurity for an entire generation. Luckily, the 5th generation has been very kind to the Screech Pokemon by presenting her with the item Eviolite, turning her into one of the bulkiest Ghost-types in the game; allowing her to not only reclaim her original title as one of the game’s best Perish Song trappers, but she even can perform one of the jobs Rotom-A lost due to its typing-change.</p>

I'd normally put a long list of calcs here, but I think the fact that she can survive a +2 Life Orb Terrakion Stone Edge speaks for itself.
The EVs for the Perish Trapper set could use some tinkering if ya feel like it since the set's not entirely focused on walling Physical Attackers as much as it is stall in general.

[Set Comments]
- The only job of 4th Gen Rotom-A’s that Misdreavus can effectively replicate in OU, but she does it very well
- Ghost-typing, Levitate, great defensive spread of 324/360/309, only 1 Base Point below Rotom-A’s Speed
- She can best any Rapid Spinner bar Starmie and Offensive Tentacruel in Rain.
- RestTalk keeps Misdreavus healthy and gives her pseudo-immunity to status, making her nearly impossible for Burned Physical Attackers and Toxic-Stallers to break
- Her base 85 Speed lets her Burn most Tyranitar & Scizor with Will-O-Wisp before they can touch her
- Normal, Fighting, & Ground immunities let her freely switch-in on two of the most dangerous types in the game
- While not particularly powerful, her STAB Shadow Ball is enough to break the subs of most Pokemon trying to set-up on her, be it Landorus or Terrakion.
[Additional Comments]
- The EVs are straight-forward. Misdreavus’ new-found bulk lets her shrug off anything Pokemon like Scizor, Landorus, or Physical Jirachi can throw at her. She can even take, a +1 Dragonite Outrage, a +2 Terrakion Stone Edge, or even have a 87% chance to survive a +2 Life Orb Terrakion Stone Edge
- While she possesses very competent Special Defense, she enjoys having teammates that can take heavy Special Attacks for her as well as capitalize on her Spin-Blocking assets and ability for force switches with hazards.
- Tyranitar’s with Crunch are big issue if she’s asleep and gets an unlucky Sleep Talk. Most bulky Ground- or Fighting-types can take care of Tyranitar.
- Heatran and other Fire-types are huge problems for Misdreavus.
- Blissey and Heatran make great teammates for Misdreavus as they can take on Special Attackers and set-up hazards.
- Swampert gets a special mention as he can take on Tyranitar & Heatran as well as set up hazards.
- Misdreavus shouldn’t be the focus of a team as she’s more of a supporter
[SET]
name: Perish Trapper
move 1: Mean Look
move 2: Perish Song
move 3: Taunt / Heal Bell /Rest
move 4: Pain Split / Sleep Talk
item: Eviolite
nature: Bold
evs: 252 HP / 252 Def / 4 SpD
[Set Comments]
- Altered version of Misdreavus’ signature strategy since Gen 2
- Breaks-apart stall teams by Mean Looking walls then using Perish Song as they struggle to even significantly damage Misdreavus
- Rather than just blocking, this set can flat-out remove Spinners like Tentacruel that can’t take her down
- Faster Taunt-users & un-taunt-able phazing moves like Dragon Tail ruin the strategy
- Taunt can prevent Whirlwind, Status, set-up, or slower Taunts
- Pain Split keeps Misdreavus healthy during the countdown
- Heal Bell can be used in tandem with Pain Split to keep Misdreavus status-free while also removing her teammates' status
- RestTalk can remove the poison walls like Chansey usually carry.
[Additional Comments]
- Works well on teams that utilize sweepers that enjoy the removal of opposing walls
- A cleric like Blissey will make a great teammate as Misdreavus is open to status without RestTalk
- Protect can score a free Perish Song turn but provides little merit over Taunt otherwise
- Destiny Bond is a last resort move that helps if Misdreavus can’t make it through the Perish Song countdown or is staring down a powerful sweeper
- Will-O-Wisp can cripple physical attackers and make them easier to trap
- Again, Misdreavus shouldn’t be the focus of a team as she’s more of a supporter
[Other Options]
- Nasty Plot or Calm Mind can turn Misdreavus into a bulky sweeper but it’s not advisable over the other sets
- Heal Bell lets her function as the only Ghost-type cleric bar her evolution
- Confuse Ray can be used on the Perish Trapper set, but there’s a lot of risk involved in using it
- Trick Room can be utilized, but Misdreavus’ Base 85 Speed is one of the perks she has over the other bulky Ghosts
- Wonder Room swaps all Pokemon’s Defense & Special Attack for 5 Turns. She’s probably the only decent user of the move bar Slowbro/king. It’s an interesting move, but has little to no practical applications as of now
[Checks and Counters]
- Tyranitar, Crunch, Pursuit, etc.
- Heavy-hitting Special Attackers like Latios, Gengar, or Specs Politoed
- Heatran & other Pokemon immune to Burn minus Gliscor & Breloom, who can’t do much to RestTalk
- Taunt cripple both sets
- Bulky Substitue users like Bulky Gyarados & Dragonite can ruin RestTalk Misdreavus’ fun
- Tricking a Choice item on her makes Misdreavus virtually useless
- Murkrow used Mean Look! Misdreavus used Mean Look! Murkrow used Perish Song!
