Hmmm...should extras occur, this could work
You know, this idea has reminded me of the Voodoo cards (and my occasional questioning about how comparable they would be to a proper Tarot deck). I'm tempted to recommend making a Telltale Tarot now (which, even if it was just the Minor Arcana, would allow an additional two cards to the planned 54 - four extra "face" cards in place of the two jokers).
There is balance in all things. Live in symmetry with the world around you. If you must blow things up and steal from those around you, THAT'S WHAT RPGS ARE FOR!
