Not just a snapshot, but a trend line
All cards depicting Shiny Pokmon in Darkness, and to Light made use of a special type of reflective holofoil which has never been used since in the Pokmon TCG
Our last review of something in this mould was Elder Sign, also from Fantasy Flight
Unfortunately, due to the way the game determines which card you get, it never picks the latter, meaning there's no way to obtain Phantom Venusaur without a cheating device (and in turn construct the Mysterious Pokmon deck in the Pokmon Dome's Auto Deck Machine, which requires two of them)
Although Jolteon was perhaps the fan-favorite, what made Vaporeon highly sought after was the beautiful contrast between the gold holographic and the blue background
Gold Pokmon cards are real, but only certain ones carry legitimate value
