On the getting returns from leasing cards out. If you play for several years and you accumulate 1000s of cards like many Magic the gathering players do then the answer is yes you can totally make decent money. If you spend $1000 and go buy the best cards in the game right now the answer is yes you can make money. Now can you make your money back and is it a good investment??? No one knows and if they tell you otherwise they are lying to you.
