If you want to buy cheap cards then reward cards market is the right place for the cheapest cards in the game. Because the cards are so cheap you can even buy maxed out common cards under 1 cents. Even the most used reward cards can't keep their price higher because of the high inflation rate of the cards. Ruler Of The Seas was trading at 5 usd and after last season reward distribution the price of this card finally crashed to 3 usd where now this card is trading at 3.46 usd. I wonder when dec will go live if the reward card prices will go because of the card burning. If it will boost reward card prices then it would be smart move to buy some 1 cent common and 2 cents worth of rare cards.
