====== The Card Store ======
Accessible from the main menu, the store allows players to buy all commons in the game or sell surplus card. 

To buy cards, players need a currency called [[hidden:hd_creds|credits]] (or creds for short). Creds can be obtained from winning single player and PvP games, or selling unwanted cards which refund about 25% of the card value. [[hidden:cardlists:misc#unique_cards|Unique cards]] and [[hidden:cardlists:legendaries|legendary cards]] can only be sold if you have more than 4 units of this card.

====== The Slot Machine ====== 
You can try it once per day : each try can reward you either nothing at all, or some credits, or a random card.

====== Hint ====== 
Random cards rewarded by the slot machine or by winning a game are not truely random : the less copies of a given card you possess, the greater is the chance to get it as a reward. On the contrary, the more copies of a card you possess, the lower is the chance to get it as a reward. Once you have 4 copies of a given card there is almost no chance that you get one more as a random reward. 

You can use this to your advantage to make the most of your random rewards : if you buy all the cheap common cards available in the store so as to possess 4 copies of all of them, then for random reward you will receive almost only the other cards : expensive commons, elites and even legendary. This is a good way to save a lot of credits (and so, a lot of time) and complete your collection.
