Here we have two different cards. The number in the top Left is the power number and the symbol in the top right is the Pillar type (Military , Government, Economy, or Culture). Each card will have different options with a price, indicated by the blue tab above the ability text box. As you can see, the higher power card has less options; this is part of the balancing scheme at work. The stronger the card the less flexible it is during the game. The Military card (red) has a power of two but can be used in three different ways. Once one of the options/abilities have been chosen, you may not use any of the other options. I really like this set up because on a given turn you have a lot to work with and can react differently depending on what happens. Although, you risk getting you card conquered when it has a lower power.
