I added a powerful Keeper to my Fluxx deck some time back that I'd share with you all. When I was making the Keeper called "Doppelganger" for my own Fluxx deck, I was going to make it an Action that stays on the table as if it were a Keeper. When I heard about the dual-identity promo cards (Flowers, Star, Robot...), however, I decided to make Doppelganger a Keeper with the picture above the name_line and its special ability below. This is similar to the Doppleganger on Hal Haag's Fluxx site. This card becomes very powerful once there are a lot of other Keepers in play. Conversely, it's fairly weak at the start of the game and it loses a lot of its power when a strict Keeper_Limit is played and/or you're the only player with a lot of Keepers. Type: Keeper Name: Doppelganger Image: (Above the line) Light-green man-shaped blob with eyes, a mouth, a " ? " on its chest, a pair of antennae, and a speech-bubble that reads, " I can be anything I see! ". Text: (Below the line) " This card can copy any Keeper that is in play and face-up on the table. However, it can only copy one Keeper at a time. This special ability only works when this card is in play and face-up on the table. "
