I have been working on an expansion for Crazier Eights: Camelot — Avalon. It will be 33 new cards that can be played by two players, or shuffled into the Camelot deck. It makes it so at least two more people can pay the Camelot game (six instead of four). If it is large enough, it will also be enough cards for a two player game.
Here are the cards:
