The Endless Demon Deck
The demons of The Vile Court are escaping the black oubliette in which they have been forgotten. In the process they are chewed, mangled, and remade.
Draw three cards and create a Mörk Borg compatible Demon to unleash on your players. These creatures are intended for use with the Masticator Gate campaign but can easily be used without that book with just a little tweaking.
