One last little tidbit
Printed as a promotional card in the September 1999 issue of Japanese toys and manga magazine CoroCoro Comic, the card is more of a child's drawing of Slowking than a serious card
But those who were lucky enough to snag these cards now have some of the rarest WOTC promotional cards ever made, selling for hundreds if not thousands of pounds on marketplaces and auction sites
For one, like most games, the enthusiasm comes from actually, you know, playing them
From there, you can pair these flicker effects with cards like Peregrine Drake, Palinchron, or a basic land (in the case of Ghostly Flicker) for infinite mana, Overwhelmed Apprentice to mill your opponents out, or Venser, Shaper Savant to return all opposing permanents to their owners hands, just to name a few of the possibilities
Collectors prize it for its gorgeous shiny Eeveelution artwork and scarcity (it was obtainable only by redeeming points in Pokmon leagues)
