Shiftry

Shiftry is one of the few Defog users in the tier with a good offensive presence. Thanks to its high Attack stat, Shiftry is dangerous when carrying a Life Orb, as it can wear down defensive Pokemon with Knock Off and act as a late-game revenge killer with Sucker Punch. Shiftry also has a good Special Attack stat and can use Leaf Storm as a mixed attacker. Unfortunately, Shiftry's mediocre Speed makes it hard to Defog against offensive teams, and its poor Grass / Dark typing which makes it 4x weak to U-turn along with its paper thin defenses means it is KOed easily. As a Defogger, Shiftry also faces competition from Flygon, which has better bulk and Speed but lacks priority, unlike Shiftry. Shiftry is also walled by common walls such as Togetic and Aromatisse, reducing its effectiveness. Nevertheless, Shiftry can make use of its typing to check Pokemon such as Alomomola, Clawitzer, Jolteon, and Delphox.
