Empoleon

By virtue of its great typing, Empoleon is able to check popular Dragon-, Fairy-, and Water-types such as Latios, Mega Altaria, and Manaphy. Access to both Stealth Rock and Defog is also very useful as Empoleon provides great entry hazard control in one teamslot, and it is one of the few Defog users with a resistance to Stealth Rock. However, Empoleon is somewhat passive; it often just sits there hoping for a Scald burn and phazing the foe. It also loses to some of the Pokemon it is supposed to check, such as Clefable, in a last Pokemon situation. Weaknesses to common offensive types in Fighting, Ground, and Electric also hold Empoleon back a little because Pokemon often carry coverage that hit it super effectively. Finally, no reliable recovery and low Speed means Empoleon is worn down pretty easily and cannot keep checking threats the whole game without Wish support.
