Tauros

With the introduction of BW, Tauros was gifted with the new ability, Sheer Force, from the Dream World. This ability boosts the damage of moves with a secondary effect by 30% and nullifies Life Orb recoil when using those moves. That, when combined with Tauros's excellent Speed and Attack stats, makes it a force to be reckoned with. Furthermore, Tauros has decent bulk, which makes it difficult to take down. Similarly to the previous generation, Tauros is known for revenge killing and sweeping late-game. However, it is weak to Fighting-type moves such as Close Combat and Mach Punch, both of which can easily stop its sweep. If you pack the right support and remove Tauros's main checks, it can be a major threat.
