Risus with Cards

The Risus Monkey is coming out of cold sleep to report on a new set of Risus rules over at the Risusiverse. The Ruminator has written rules for playing Risus with a deck of playing cards here. They are supposedly based on some old TSR game. To me, they greatly resemble the rules for one of my favorite games of all time - Castle Falkenstein! I've always had a thing for card-based systems, though I do confess that I have never had great success using one in play. But the idea of using cards seems rather cool. For certain settings and genres, like Deadlands or Falkenstein, they just seem to be especially appropriate.
