With its signature Water / Ghost typing, Frillish finds itself in a good spot in the metagame. This is thanks to having the ability to take on physical attackers such as Onix and Bunnelby while punishing Knock Off users such as Mienfoo, Pawniard, and Ferroseed that may try to switch in with Will-O-Wisp. Thanks to Hex, it is also able to deal reliable amounts of damage to Pokemon that it has burned to make it quite useful offensively. Cursed Body works well with Recover, as it makes it difficult to keep attacking Frillish if there is only one move that can hit it hard. However, it is weak to Knock Off, so it is beneficial to have Pokemon such as Mienfoo or Spritzee on the team to soak up Dark-type attacks from the likes of Pawniard or Vullaby.
