Certain Pokemon are good for certain reasons, and even that determination of "Good" varies with the user. Some may like a Pokemon because it looks cool, or because its shiny; it all depends. If your asking about how good he is in battle, then Id say that he is good againt any Pokemon with Def<Atk, and a neutrality to his Normal type moves especially Facade. Of course, hes not going to kill a Dragonite or something. He's too weak in comparison to Dragonite. But compared to a Pikachu, hes good. So its all a matter of opinion, whether Smogon says so or not.
