COUNTERFEITER You have the Power to Defraud Whenever you reveal a card, you may
immediately play a compromise from your hand to replace it. The compromise
is then treated as the original card. You then put the first card back in your
hand. You may not use it again that challenge. You may counterfeit any
number of times per challenge.

The Warp Alien Power database has over 2000 entries you can look through, including every offically printed alien (search by author, origin, expansion, variant, and more). Just click on "Homebrew of the Day" to access the Amazing Alien Database. If you play Cosmic Encounter long enough, you eventually find yourself in The Warp.
Normally, you wouldn't find this many zombies in the warp...
