I believe this came about because they wanted a mischievous creature on the back that punished the opponent for not having enough cards in their hand, and flavor-wise, that felt a lot like a faerie (it was an imp when it was on Equilor)
A number of Shining Pokmon are in the set as well, such as Shining Celebi, Shining Typhlosion, Shining Lugia, and Shining Entei
I was running out of pages in my binder anyway, and no one ever wanted to play, so I figured Id stick to the video games
In fact, many of the most valuable Pokmon cards are graded by Professional Sports Authenticator (PSA) on a scale from 1 to 10, with 10 being a never-used, mint condition card
With green ramp decks the momentum gain from having them out earlier is very significant
