Pentology by Trevor Cram is a 60 card deck system of fantasy symbols. Trevor supplies a number of games to start with, but are hoping for more contributions.

Games range from 1 to 3 players. The deck lends itself to storytelling games, as well as a small amount of combat mechanics (RPS). I think it’s still undergoing beta testing; anyway, there’s no way to buy a deck, just yet, except to ask to be a play-tester.
