Honestly, they should put in a system that allows you to trade cards to somebody else in your guild. You both can send a request for trade and then if both accept, then it is granted. There are so many rare cards that I keep getting duplicates instead of new stuff and it would be nice to be able to trade to other members. Selling them for 500 gold is not enough reimbursement for constantly getting the same rare in a random pack.
