Fluxx Blanxx (no amazon sales)

Now you can add your own zany ideas to the crazy game of Fluxx! Each pack of Fluxx Blanxx contains one of each of the five card types: Keeper, Creeper, New Rule, Action and Goal. Cards are "halfway-blank" with standard-issue text and the stripe of color. Card backs for all Fluxx games (except for international versions) match, so you can use these in any deck. Just grab your trusty permanent marker and customize the fun!

You may want to get more than one pack so you'll have enough Goals to integrate your new Keepers into your deck. If you are looking to create a whole custom deck by hand, you'll need 20-24 packs. You can check the card lists for Fluxx and Zombie Fluxx for ideas about card-type ratios and core rules to include.
