Gardevoir

Gardevoir's high Special Attack stat and good offensive typing of Psychic / Fairy make it a hard Pokemon to switch into, especially for teams that use less sturdy Fairy checks such as Forretress and Steelix as their sole Steel-type. In addition to its main attacking moves, Gardevoir gets access to useful support moves, mainly Healing Wish. Moreover, Trace is a great ability on Gardevoir, as it can copy useful abilities such as Levitate from Flygon, and Regenerator from Slowbro. However, it has pitiful Defense, which makes it revenge killed quite easily and 2HKOed by most neutral hits. Although it outspeeds most bulkier Pokemon, there are faster Choice Scarf users in the tier, such as Flygon, and its unboosted Speed stat makes it slower than most offensive Pokemon. Setup sweepers such as Barbaracle and Dragon Dance Zygarde-10% are also faster than Choice Scarf Gardevoir after boosting, making it imperfect at revenge killing.
