Gyarados with Taunt stops Rev dead in its tracks. The intimidate and decent defensive capabilities Gyarados has makes him the almost perfect Rev counter. Taunt stops him from using Bulk Up + Rest and Dragon Dance away as the main moves Rev uses is Shadow Sneak and Hammer Arm but they don't do much damage towards Gyara. I've also seen Wobba do alright on him. He can take a couple of Shadow Sneaks and Encore his Bulk Up/Shadow Sneak/ etc. And bring out a counter to that. (Tyranitar)
