You are looking at a card with a code for a shiny gengar.
The shiny gengar is exclusive to gamestop in the USA. They are said to be limited to 50 per gamestop, and As of right now you can only get one if you pre-order pokemon alpha sapphire or omega ruby. I got a few from pre-ordering Pokemon Alpha Saphire for myself and siblings. Were not going to use the codes, so figured I try here. If the add is still up, I have them.
It is a Shiny Gengar for use in Pokemon X/Y. This Gengar will come holding a Gengarite Mega Stone, allowing it to Mega Evolve into a Shiny Mega Gengar.
The card is unscratched and will send the code via Message on here. PM me if interested.
