Most games tend to come with arbitrary ways to decide who is the first player. The Sorter Deck is afun way to select first player based on the “short straw” mechanic. I originally wanted to just use cocktail swords as a mechanic in a game but slowly developed the idea of a small deck of cards.  The cards also allow you to divide groups into teams and sort players in a number of different ways. I have also been toying with some larger cards that add in some Tarot like story telling and perhaps some mafia style identities. It is another work in progress, but works quite well. The larger tarot versions are currently using some licensed vintage clipart.
