Sometimes l check the market to see which cards got cheaper and which got more expensive. At the moment most of the beta cards went down except the legendary summoners. You can now buy maxed out beta cards at 20-30 percent discount and even 50% discount. If before cheapest cards were trading at 3 cents now you can buy cheapest cards for just 2 cents. I don't know if it's a good investment to buy 2 cent cards because these cards are the least used cards in game therefore only few people need to buy them. In my opinion buying Stonesplitter Orc at 4 cents is a good idea because it's a rare card and it's a powerful card to play with.
