Sadly, that is NOT a joke. I was reading this thread to get a better idea of what they were planning to do in regards to stat weighting (see yesterday's post for an explanation), and the subject of Eviolite Slowbro came up. So I took a look at the stats to see how bad it was, and believe it or not, it's its FOURTH most common item, at a whopping 2.7%. If you ever needed proof that the situation's gone so out of hand that the current weighting system just doesn't work anymore, well here you go.
I do find it weird, however, that no one in that Smogon thread seemed to realize that it was the whole evolve-into-Slowking schtick rearing its ugly head once again, instead suggesting that it might have to do with niche Trick uses. Can't blame them, though, really, most normal people haven't entertained the idea of Slowbro evolving into Slowking since gen 2. Still, it's pretty clear to me that it has everything to do with that old misconception and nothing to do with actual utility, and should count as a candle. After all, aside from PorygonZ and Dusknoir (which evolve from two of the best Eviolite users around), every other Pokémon in the top 250 for whom the Eviolite appears on the list is NFE, and even these two have an Eviolite rate of less than 0.5%. So if fully evolved Pokémon + Eviolite + Trick really was a thing, do you really think the Eviolite wouldn't be seen on anything but Slowbro, the one fully-evolved Pokémon people might think is not one?
