Supply
Magic cards are goods that are both used and consumed, and they are collectible. Due to this mixed utility, their price is determined by a variety of factors. Even though all the cards cost the same from the company's perspective, they are not worth the same from the market's perspective. What's key to point out is that in this system there are two main parties: the supplier (Wizards of the Coast, a subsidiary of Hasbro) and the people who buy cards/product. All the cards that end up on the secondary market as singles have to have come from somewhere, namely sealed product. Wizards' product line includes product whose content is random or semi-random and some whose content is fully transparent.
Let's assume there is a product with a single card that's desired by people, and the card is known to be in the product. A good real-life example of such a situation is a product called Commander 2013. It consisted of five separate decks, and the release price of each deck was the same. However, one of the decks, Mind Seize, contained

Let's focus on the card itself and what models its price. First comes the availability and the print run of the product it can be found in. The more of the product is available on the market, the lower the price of the card. Not every product's print run is the same. Wizards tend to diversify the quantity in which they release products. Sometimes they print to demand, sometimes they limit the print run. Additionally, the question is how many copies of the desired card one can find in the product, which also varies. In the aforementioned Mind Seize deck, there was one copy of
Of course most cards come from booster releases, where calculations become tricky. For example, the average draft booster box of Dominaria United contains about 0.45 copies of the regular version of
Sometimes, a card gets a reprint, which means that a new version with the same name and function is put into another product, but with a different symbol indicating when it was printed. Usually, this decreases the price of the card due to the increased supply. However, it is not unheard of that the original printing still holds its price due to its uniqueness. Arguably, the most emblematic example of that are basic lands. Most of them are nigh worthless and you could tear one into pieces without hesitation. Still, you can hardly get a Beta basic
On top of that, Wizards sometimes reprint cards not in widely available products but as promotional giveaways: as a reward to Magic Judges, for instance, or for participation in certain tournaments. This process, however, tends not to influence the price heavily as the quantity influx is too small of a proportion compared to the whole supply.
Demand

The aforementioned factors are the supply factors. As far as demand is concerned, there is a different set of aspects to consider. One basic factor is how frequently the card sees play competitively at tournaments. The more it is played or intended to be played, the higher the demand and, hence, the price. What makes this tricky to evaluate is that a card's playability changes dynamically over time. Players construct decks with the goal to have the best chance at winning. Other players may react and create a deck that specifically aims to beat the currently dominating decks. Through this process, the perceived best decks and best cards change as players keep adapting to what others are doing. Therefore, some cards have their peaks of playability and popularity, as well as troughs, which directly translates into peaks and troughs in their price.
From time to time, a card is deemed too good and is then banned from competitive play. Consequently, its price decreases as the supply stays the same, but demand plummets: people no longer need cards that are illegal and can't be played. Additionally, there are speculators who buy out cards in order to create artificial scarcity and inflate prices to later trade them off at higher price points. Last but not least, the card's physical condition is a major factor. The condition can be as pristine as if the card had just been opened from a fresh booster pack, or it can be scratched, inked, or bent. This heavily influences the pricing. All the aforementioned factors contribute to the current and ever-fluctuating prices of Magic cards.
In Practice

To illustrate the point, let's use a simple example: You go to your local game store and want to buy
Once a card is printed, the market establishes a price for it, which then varies over time. One way Wizards themselves can influence this from their side is to increase supply. However, rather than put more of a given card into one set (that is, lower rarity), they can reprint it and put the same card into another set. In practice, this means that, functionally, the same card is available in different products, but with cosmetic differences such as the set symbol to distinguish it from the original printing. An example for a price-reducing reprint would be
There are sets exclusively designed to contain a lot of reprints of expensive cards, broadly referred to as Masters sets. Naturally, what determines whether the reprint affects the price are the same factors mentioned above: rarity, probability, and whether the set is opened heavily, increasing supply on the market. As an example of a reprint that did not impact the prices, I can point to Secret Lairs with fetch lands. The cards were indeed in high demand, but a reprint as a premium product in a very limited quantity at a high cost did not lead to a price decrease on the secondary market, much to players' disappointment. (Later reprints in a Masters set did.)
In Summary

To sum it all up, most important factors that affect a card's price include:
- Rarity
- How much the set is opened
- What the print run of that set is
- Playability of the card
- Number of copies players need
- Condition of the card
- Reprints
- Bans
I hope this piece explained what factors affect the prices. Stay tuned for more articles on the basics of finance. For now, hold my hand, and let's pass the turn together. Cheers!
