Electivire has two things going for it: the best coverage in OU and one of the most useful abilities in the game. Unfortunately, due to a lack of raw power and Physical STAB, Electivire was never going to overhaul the metagame. Because of a lack of Physical STAB, Electivire often plays mixed, using Thunderbolt, Hidden Power Ice, Flamethrower alongside Cross Chop to gain super effective damage on most every Pokemon in the tier. Other sets will go completely Physical, opting for the elemental punches and Earthquake. Electivire's greatest weapon is its coverage, but it has an added bonus in the ability to boost its Speed. Electivire can easily switch in on a predicted Electric-type attack (even Thunder Wave) and begin wreaking havoc. It also sports a resistance to the most common form of priority in the tier, Scizor's Bullet Punch. It is often used in a bait-and-switch strategy, getting free boosts from Electric-type attacks aimed at a Gyarados or Skarmory. Offensive teams are often easily swept, as often their fastest Pokemon is Scarfed Rotom-A, which is slower than Electivire and cannot use a STAB Thunderbolt on it. Until Electivire is revealed, it remains a dangerous secret weapon.
