Pheromosa

Pheromosa can be a threatening attacker in the right conditions, usually on hyper offensive teams, with powerful attacking stats, colorful coverage, and a deadly All-Out Pummeling that helps with weakening Steel-types for its allies as well as dealing a huge blow or even threatening an OHKO against many Trick Room setters such as Diancie, Bronzong, and Porygon2. Its ability to outspeed the entire unboosted metagame naturally is also very positive, and this holds especially true when Pheromosa is backed up with Tailwind support. U-turn is also a very helpful tool, letting it pivot out of rough matchups while still doing notable amounts of damage. However, non-existent bulk makes Pheromosa susceptible to drop to nearly any hit it takes; U-turn and Protect help mitigate this issue, but it's still not enough to make up for it. This is especially glaring when the opponent manages to successfully use up their method of speed control, be it Tailwind, Icy Wind, or Trick Room, as an outsped Pheromosa is a fainted Pheromosa most of the time.
