Should I buy magic cards?

Most people want to win when they play Magic, so a large portion of the player base is always going to be chasing the latest and greatest deck. If a particular card ends up seeing play in one or more really good decks, demand goes up. When demand goes up, value goes up. If it's on the reserved list and won't ever be reprinted, that further increases its price since its supply is limited, regardless of increasing demand. As a result, MTG cards are valuable collectibles. The right selection of cards can bring in many thousands of dollars during resale. But you need to consider many factors, such as the condition, rarity, and uniqueness of the card. It is they who provide the high price of the MTG card.
