Psychic is an interesting case. I've always thought the type and a lot of the Pokemon were pretty cool, but they don't seem to find their way onto my team with any great frequency. I thought maybe this was because they were rare, but turns out Psychic is actually a very common type, so...I don't know. Of the Psychic types I have trained, though, they've all been absolutely wonderful (though it should be noted that two of them are legendaries ), so I'd love to have more Psychic types in the future (which they can probably see).
Bug type is up next.
