Bold School was the one who claimed to have game design knowledge (and thus claimed to understand it better than the average person) before anyone so I don't know why you're singling Buzzwole out for this.You can talk about your opinions on roaring moon, but don’t make it seem like having experience in game design makes you any better at understanding team composition. Game freak makes stupid balancing decisions all the time, and they probably have much more experience in game design than you do. Only way to actually demonstrate thorough understanding of the meta is to excel on ladder or in tours, and it seems like you have done neither.
BTW surprise factor alone does not make something "good", it needs to have real consistent and applicable value beyond initial surprise or else it loses any effectiveness once any kind of awareness of it catches on.
