The RPC54 system is a role-playing game system that uses poker cards to determine the effects of actions. The cards are numbered 1 through 13 and have four customs suits that reflect the different environments where the characters might find themselves. This system is used in Burning Games LTD's game Faith: the Sci-Fi RPG.
Each player, including the gamemaster, draws a hand of seven cards from a poker deck. They will use those cards to try to prevail whenever they want to stop someone from doing something or someone tries to stop them. This mechanic allows for luck management, as the players can choose which cards they play and when, and is an equaliser in the sense that all players must play through the same deck eventually, thus giving them equal or very similar chances of success or failure.
