Quick Answer
Carl Sagan's Joint is a special Artifact card that lets you swap it with any Artifact or Gadget another player has on the table, once per turn as an extra action.
Why This Promo Card Stands Out
Carl Sagan's Joint debuted as a promo card for the Summer Festivals of 2004, making it a collector's item for Fluxx fans. It works in either type of Chrononauts deck, so you can use it in both classic and expanded versions of the game.
The card's flavor text references Carl Sagan's well-documented enjoyment of marijuana, which adds a humorous and memorable touch to gameplay. This makes it a conversation starter at game nights.
