Dragon Cards is a popular game in many taverns.  The deck has 6 suits (coins, crowns, moons, shield, skulls, and tomes).  Each suit has 12 cards (uniquely named with a Tarot-like feel, but that's not relevant for this game).  There are 2 wild cards, a Mimic (which copies a card in your hand), and a Dragon (which causes you to lose that hand if you get stuck with it).

The rules are explained in the extension, and the DM can click a button to post them to the chat window.

The DM selects which characters (and optionally NPCs - use /dc to add some) will play.  Players can control one or more characters; the DM can control any.

It should work in any ruleset, but I've only tested it with 5E so far.  It uses the Party Sheet to get the list of possible players, and (optionally) automatically deducts ante (or adds winnings) to the characters' inventory.  The ante amount is configurable.
