The Endless Demon Deck

From the DriveThruRPG listing: 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 upcoming Masticator Gate campaign (releasing in March 2021) but can easily be used without that book with just a little tweaking.
