Mandibuzz

Mandibuzz's typing separates it from other defensive Flying-types through its ability to check Dragapult. Its great bulk and access to Roost also allow it to check common threats like Rillaboom and Kartana. It is a good Defog user, with Foul Play pressuring common Stealth Rock users like Landorus-T and defensive Garchomp, although it loses to them in the long run due to their moves like Toxic and Knock Off. Foul Play also discourages physical wallbreakers like Rillaboom, Kartana, Dragapult, and Excadrill from setting up. Since it is reliant on Heavy-Duty Boots, Pokemon that it otherwise reliably checks, like Kartana and Rillaboom, can pressure it more effectively after using Knock Off. Due to the number of threats it can check, it can often be overwhelmed during the course of a match, which forces it to use Roost very often. Its reliance on Foul Play to check certain threats can leave it rather passive as well.
