Bunnelby

Bunnelby is able to use Huge Power to effectively wallbreak and clean. Aditionally, its decent Speed in conjunction with a Choice Scarf or Sticky Web support allow it to outspeed many important threats and effectively revenge kill as well. Due to its high Attack and coverage it is hard to switch into, but some common Pokemon, such as Onix, Ferroseed, and Pumpkaboo-XL can still easily come in. Additionally, Fighting-types such as Timburr and Mienfoo can easily force Bunnelby out, forcing Bunnelby's team to lose some momentum, and if it is being run on an offensive team, that can be hard to deal with. Finally, it has very low bulk, meaning it is very hard to get it in without U-turn or Volt Switch.
