Vigoroth

Counter is an awesome move for PvP, and even without STAB performs significantly better than Scratch. 

Body Slam is the main charge move for Vigoroth, benefiting from STAB and enabling heavy shield pressure thanks to its low energy cost and good DPE. Rock Slide is a good move and provides further coverage against Flying- and Ghost-type Pokemon and is Vigoroth's preferred second Charged Attack. Bulldoze is a poor move, though it has utility in dealing additional damage to Steel-type Pokemon. Brick Break is pretty bad since it is somewhat redundant as Counter already deals good Fighting-type damage, and the Defense debuff isn't strong enough to make it worth using.
