If you purchased your cards prior to the launch of the Expansion Pack, it is possible that not all of your Cards are enabled in your online account. To see what your deck looks like, log in to your Corsava account and click on the Cards tab at the top right side of the page to view all of the cards. The card definitions will appear if you click on an individual card. 

Click on Customize Your Deck at the top of the page under the heading Corsava Cards. You will see a list of your current deck, with Disabled Cards listed at the top, then Enabled Cards below. Simply click on the card name in Disabled Cards and they will move to Enabled Cards. You can also shift cards from Enabled Cards to Disabled Cards by clicking on them.
