I disagree, for the reason I listed: the Psychic types that are in OU, are, for the most part, not there because they use Psychic-type attacks. Most Starmie and Slowbro sets don't even use Psychic, and Exeggutor and Jynx only use it because their movepools are shit. Alakazam is the only Pokemon in OU to use Psychic with the main purpose of being offensive. The reason those five Pokemon are in OU is because a) Psychic type is so good defensively, and b) they all have incredible stats - particularly Starmie, Slowbro and Alakazam. Like, there's a reason Hypno isn't OU, and a reason that Mr. Mime isn't OU - they may be Psychic types, but they have terrible stat-spreads (and thus are anomalous amongst Psychic types).
