This promo card works in any Fluxx deck.
It reads, "If you are wearing tie-dyed clothing of any kind, Draw and Play 1 extra card per turn."
This was released as a peel-off promo postcard for TableTop Day 2014. We reprinted it in 2020 as a loose single.
Threw this into our Fluxx games and now my roommate deliberately wears her tie-dye hoodie every single session just to draw the extra card. It's a peel-off promo card, so it's a bit flimsier than the deck cards, but it shuffles fine in a sleeve.
My friends and I always play in our old tie-dye shirts, so this card gives us a free extra draw basically every turn. It slots into any deck and the peel-off back came off clean without tearing. Fun little bonus if your group already owns some groovy clothes.
Peeled this promo card off the postcard backing and it slotted right into my Fluxx deck with no issues. The tie-dye bonus is a fun little rule, and my group actually started wearing tie-dye on game nights just to trigger the extra draw.
