This special Goal card can be used in any Fluxx deck, but only if that deck has at least two Tree Keepers.
It says, "The player with 2 or more Tree Keepers in play wins."
This card was released at Origins 2006, along with the Pine Tree, the Palm Tree, and the Fruit Tree. (The theme was trees because the new release at that time was Treehouse.) Other Tree Keepers that work with this card are the Tree from Family Fluxx and Trees in EcoFluxx.
When purchasing large quantities please order in multiples of 25.
