This is a Keeper you can add to any Fluxx deck. It says, "If any two players each have a Keeper needed to win by the current Goal, the game ends with both players being the winners. If not, draw 2 cards." This card was published in 2015 to promote the release of Adventure Time Fluxx. It is a card that peels off off a postcard.
The stripe-side of the card is shiny, due to the peel-off method, but this will not affect game play.
