From the Looney Labs webstore:
This special New Rule card works in any Fluxx deck.
It says, "Whenever you draw a card, you may choose to take the bottom card of the discard pile instead of the top card of the draw pile. It's OK to look at the bottom card first."
This card was released at Origins 2005, to help promote the release of EcoFluxx. (This card also appears in EcoFluxx.)
