Fluxx: The Traitor

Fluxx: The Traitor is an expansion card released in 2009 as a promotional postcard that can be added to any Fluxx game.

Text on the card:
You cannot hold this card, but must place it face up in fornt of you as soon as you get it. If you drew it, immediately draw another card to replace it.

If you have this card, you cannot win by meeting the current Goal. However, if another player meets the Goal, you win instead of them.
This card moves to the current player whenever a New Rule is played.

When you play "The Traitor", you draw cards from the deck until you draw a Keeper or Creeper (in which case you keep only that card) or you stop drawing (in which case you keep all the cards drawn).
