It's Mismagius!
Many of you who play UU will know this Mismagius. Hailed as one of the best stallbreakers in UU, the only typical member of a Stall team who will be able to defeat this beast is Drapion - who Mismagius can escape from alive. Additionally, she fares well against other Mismagius and others I will list in this analysis.
I have tested this set and it works extremely well as a stallbreaker.
Additionally, the EV spread was originally 252 HP / 40 Def / 216 SpD (Calm), but I see that it works much better with those 40 Def EVs put into SpA because of speed and burn relieving most of the physical damage it receives.
Credit to Thund for the set.

[SET COMMENTS]
<p> Mismagius is often hailed as the beast of UU, with a set of Substitute and Calm Mind that is nearly impossible to stop, penetrating even Chansey. This Mismagius takes a more defensive approach, while still being able to defeat the typical members of a Stall team.</p>
<p> Taunt is the core of this set. Most members of a typical stall team, such as Chansey and Roserade, rely on statusing Mismagius in order to come out on top. Taunt will stop any attempts to paralyze or sleep Mismagius, respectively, while also halting Roserade's Spikes.</p>
<p> Taunt's main use, however, is stopping recovery. In a Stall team, most, if not all, members will have a method of healing. Mismagius base 105 Speed means it's more than likely able to outspeed the opposition and Taunt it before it replenishes it's health. Mismagius makes a wall-breaker of sorts by preventing heal while chipping away at health points using the combination of entry hazards and burning the enemy through Will-O-Wisp. Will-O-Wisp also defends Mismagius from Registeel, whom it will beat 1-on-1 through the use of Shadow Ball, Taunt, and Will-O-Wisp, and allows Mismagius to escape from Drapion to live (which is ironic because it is a Ghost!) another day.</p>
<p> Pain Split is Mismagius' only form of healing, but as most members of a Stall team have gargantuan HP, like Chansey and Altaria, Mismagius will be able to thrive at high health. Although it may not seem that good because of this Mismagius' large investment in HP, keep in mind that 4 HP Chansey still has 642 HP. Shadow Ball is the obvious choice of attack, backed up by STAB and a decent base Special Attack, will help "haunt" the target of the attack.</p>
<p> Registeel is often considered the best counter to Mismagius, however this set is able to defeat the robotic. Mismagius is a magnet for Registeel, who may get burned on the switch-in by a timely Will-O-Wisp. Taunt will then stop any attempts to paralyze Mismagius with Thunder Wave, as while paralyzed Mismagius is an easy target for physical attackers. Taunt also stops any attempts to Curse or Rest. Shadow Ball will do roughly as much as Iron Head while Registeel is Burned, while the burn itself chips away at Registeel's health.</p>
<p> Another common check to Mismagius is Azumarill. Mismagius will likely lose 1-on-1, however Mismagius can burn it, crippling both it's power and its bulk and making it all the more easier for teammates to handle it.</p>
<p> The EVs of this set are rather simple. A Calm nature boosts up Mismagius' excellent Special Defense, while 252 HP EVs are put into HP to maximize it's dual survivability. 216 Special Defense EVs help Mismagius sponge the assaults of (Haze) Milotic and Roserade, two common members of a Stall team. The rest of the EVs are put into Special Attack to juice up Shadow Ball. An alternate EV spread would be 252 HP / 144 SpD / 112 Spe, which outruns Jolly Absol and can burn it, turning Night Slash's OHKO to a 2HKO and, along with Life Orb, severely lowers Absol's lifespan. </p>
<p> Because this Mismagius can shuffle a team so well, entry hazards are extremely recommended. Mismagius' Ghost typing also means it can protect the hazards from being spun away, and fares well against the most common Rapid Spinner, Hitmontop.
<p> Spikes Roserade can easily set them up with it's offensive prowess forcing many switches, and durable Pokemon like Mesprit or Registeel are perfect to set-up Stealth Rock. Toxic Spikes are not recommended because of the large amount of UU that is immune to it and can even absorb it, as well as it's interference with Mismagius' Will-O-Wisp. </p>
<p> Offensively and defensively, Clefable is a great choice with Mismagius. Clefable's Life Orb Double Edges and Fire Blasts can seriously harm any member of a Stall team, and thanks to Magic Guard it avoids damage from Life Orb, Double-Edge, entry hazards or Sandstorm, which would break apart any other pokemon. Clefable's only weakness is a type Mismagius is immune to, and Mismagius' Ghost weakness does nothing to Clefable (although you still need to watch out for Dark typed attacks). Registeel forms a good defensive pair with Mismagius, giving it Stealth Rock and a resistance to both of her weaknesses, while Mismagius prevents the Stealth Rocks from being spun, and absorbs Ground and Fighting attacks that harm Registeel (and sponges most Fire attacks thanks to good SpD). </p>
