If you have more than one copy of the same Card, you can send them to a friend and help them with their progress.

In the Album menu, the Cards you have multiple copies of are marked with a "+1" (or a higher number, if you have more than one extra copy).

• To trade an extra, tap on the Card you'd like to trade.
• At the bottom of the Card, you will see a “Send to a Friend” button. Tap that button, select a Friend, and send the Card on its way!
• If you click the "Make an Exchange" button, the person you sent the card to will send their card to you within 24 hours, and if you approve, the trade will be completed. If you don't click "Make an Exchange" button, you'll send the card one-way.
• Remember, you must be connected to Facebook if you'd like to send Cards!
• Keep in mind that there is a daily limit of 5 trades.
• If you want to trade your cards using the Facebook group, you can join the group through this link and read the guide section within the group to learn how to trade. Remember, if someone proves that you scammed them, you will be permanently banned from all groups and the game!

You can also exchange excess Cards for a reward using the "Card Trader" option found within the right bottom Album menu.
