The rewards system have been implemented, from this interface you can claim your rewards and check the progress you have on them, keep in mind that once you claim a reward your album will be locked and you won't be able to withdraw cards that you don't have repeated anymore.
Is now possible to mix 9 of your repeated cards to get a random one of the same rarity, the card you get from this exchange could be a card you already own but you can guarantee a new card paying a 2 diamonds fee.
