Splice Pirateology Card Game (2007)

This set building card game comes in a beautiful round tin and has die cut cards. The gems are just thin card stock.
From the back of the tin:
Choose your Gemstone and battle your opponents to find the missing pieces of your treasure map in this swashbuckling card game. You may be the most notorious pirate around, but beware the Hurricane, Skull and Black Spot Cards that may hinder your passage across the high seas. Collect gold booty as you go and use it to bargain for the treasure map cards that will lead you to victory. Always remember, never trust a fellow pirate - it's every seafarer for himself. And may the bravest Pirate win!
