Mismagius is a deceptively powerful force, especially in the UU tier where she really shines. With three immunities, very good Special Attack, Special Defense and Speed, and a varied movepool, Mismagius has the ability to wreak havoc against opponents. Mismagius is a very frail Pokemon in terms of physical defense, though, so even weaker physical attacks will hurt her very severely. Her base HP isn’t anything to write home about either. Still, with excellent support options and powerful offensive potential, she is a welcome addition to any team that needs her specific touch.
The biggest advantage that Mismagius has over most of her Ghost-type brethren is the combination of powerful Special offense, defense and speed. Very few Pokemon in UU have a chance to outrun Mismagius, and those that do have to contend with powerful Special defense and return fire from a strong Special offense, each stat at base 105. Physically, though, Mismagius has much to be desired. The rest of her stats are all base 60, so she will not survive many physical hits, nor will she do much of any damage with physical attacks. Instead, it is best to focus on making her as bulky, fast or hard-hitting in the realm of Special, rather than Physical, as you can.
Speaking of making her that way, meet two of Mismagius’ best friends: Calm Mind and Nasty Plot. Nasty Plot improves Mismagius’ Special Attack by two stages, making her attacks hit with terrifying power, where Calm Mind increases both Special Attack and Special Defense one stage, boosting her overall survivability along with her offensive presence, which is arguably better since her base HP of 60 leaves very little margin for error.
Mismagius has fairly decent offensive type coverage, with Thunderbolt, Psychic, Shadow Ball and Energy Ball being her standby offensive options. Her support options, though, are very interesting. Pain Split is a particularly effective option for self-healing, with her low base HP only helping her with that particular attack. Heal Bell helps dispel status conditions, something any team falls in love with. Mismagius also has the ability to use Wonder Room and Trick Room, two five-turn field effect attacks that either force each Pokemon to swap its defense and special defense or cause slower Pokemon to move first, which can be massively disruptive to an opponent. Magic Coat, Skill Swap and Trick are also some options to choose from. Overall, Mismagius can indeed do a lot of sheer damage, but she also has a niche in being a mischievous little trickster as well.
Mismagius’ best partners are those who can cover her weaknesses. Physically bulky Pokemon or physical walls can cover Mismagius’ crippling weakness to any physical hits, and Dual Screeners can help her with Reflect. Of particular note is Lucario, who resists many of the attacks that would be directed at Mismagius and can hit Dark types who would otherwise have nothing to fear from any Mismagius without Hidden Power Fighting. Mismagius will also cover bases for several other Pokemon who need her, such as Steelix. The nice thing about a pairing with a Pokemon like Steelix or other Earthquake Pokemon is that the Earthquake will miss Mismagius entirely. Just remember to pair her up with partners or define her role on a team in a solid manner and she will never fail to impress.
