Spectrier

Once Calyrex's loyal steed, Spectrier now haunts the metagame as a fast, strong special attacker that can snowball with Grim Neigh. It has great base Special Attack and Speed stats, OHKOing targets like Mew and outrunning threats such as Landorus and Naganadel, along with a STAB Shadow Ball for excellent neutral coverage. After a Nasty Plot boost, Spectrier is difficult to slow down due to Grim Neigh making it stronger with each KO, along with a Fake Out immunity. Tools that help Spectrier set up, such as Fake Out and redirection from Pokemon like Zeraora, Blastoise, and Amoonguss, are excellent, as is Urshifu-R, which beats the Dark- and Normal-types, like Incineroar and Porygon2, that are immune or resistant to Shadow Ball. However, without a boost, Spectrier can struggle to break past bulkier Pokemon like Tapu Fini and Incineroar, the latter of which doesn't fear Shadow Ball. Shadow Ball is also its only good attack, which exacerbates the issue of needing a boost to snowball and be optimally effective. Spectrier also has issues setting up a Nasty Plot, due to the being frail enough to fear spread damage even when given redirection, and Life Orb recoil leaves it vulnerable to priority moves such as Rillaboom's Grassy Glide. To top it all off, Spectrier relies heavily on its Speed, which makes it weak to opposing Tailwind or Trick Room, while also being threatened by the two Pokemon naturally faster than it, Zeraora and Dragapult. Trick Room teams in particular are a huge headache due to Porygon2, one of the best Spectrier answers, being a mainstay on those teams.
