Game description from the publisher:

Does life seem drab and humdrum? Let the cyclone of Oz Fluxx, the ever-changing card game, whisk you away to a magical world of fun and wonder! Mingle with Munchkins, make new friends, help them with their quests, and follow the Yellow Brick Road to seek the Wizard's help for your own heart's desire – but beware the flying monkeys, fighting trees, and fields of poppies! Don your green spectacles to enter the Emerald City, and keep a bucket of water handy: You never know when you'll run into a Wicked Witch that needs melting. Next stop...the land of Oz!
