Scrafty

Scrafty is a unique Pokemon that provides multiple valuable qualities to its team: Knock Off can remove items to soften up opposing teams early-game, Shed Skin makes it one of the best status absorbers in the tier, Bulk Up and Rest let it act as a late-game sweeper, and its great Special Defense and few weaknesses let it stand up to threatening wallbreakers such as Starmie and Alolan Exeggutor. However, Scrafty is completely countered by defensive Sylveon, which makes it deadweight in that fairly common matchup. Additionally, it can be a sitting duck for the tier's many threatening Fighting-types and requires a lot of team support to make up for the switch-in opportunities it often gives Passimian and Toxicroak. It also struggles with other defensive staples such as Mantine and Vileplume and is generally slow to make progress.
