Clefable

Clefable’s powerful ability, Magic Guard, makes it an incredibly attractive option, rendering it immune to entry hazards, any residual damage, and even paralysis. Although Blissey, a similar Pokemon, has greater bulk, Clefable still has very good Special Defense, which is high enough to check almost all special attackers in the tier like Empoleon, Heatran, Choice Scarf Rotom-A, Starmie, Suicune, and Zapdos. In addition, compared to Blissey, Clefable has some additional support moves like Knock Off and Encore.

That said, Clefable still has a few weaknesses that can be exploited; namely, it is a passive Pokemon. Offensive momentum can overwhelm Clefable, and while its physical bulk is not awful by any means, many physical attackers are more than capable of getting rid of Clefable in one to two hits. Clefable is also vulnerable to setup sweepers with Lum Berry as well as Taunt users. Regardless of these flaws, Clefable fits onto a wide variety of teams, boasting a larger versatility than meets the eye.
