In addition to the Elements and Compounds, we have specially created stimulus cards which would bring even more fun.  If you are lucky (or unlucky for that matter), you may draw a Fate or Mission card during your turn:

• Mission Cards: The event card gives a problem for the two players to solve "in partnership" such as creating a compound even while you are still fighting with your opponent. The first player to create an answer to that problem gets to increase his or her IQ by the amount written on the card. You get to place the compound in the first row and boost your army.
  
• Fate Cards: They add flare to the game, sometimes helping you, and sometimes not (who said life was fair). For example, the Tsunami fate card destroys all cards on the third row!
