Magic the Gathering

Each game represents a battle between wizards known as "planeswalkers", who employ spells, artifacts, and creatures depicted on individual Magic cards to defeat their opponents. Although the original concept of the game drew heavily from the motifs of traditional fantasy role-playing games such as Dungeons & Dragons, the gameplay of Magic bears little similarity to pencil-and-paper adventure games, while having substantially more cards and more complex rules than many other card games.

New cards are released on a regular basis through expansion sets. An organized tournament system played at an international level and a worldwide community of professional Magic players has developed, as well as a substantial secondary market for Magic cards. Certain Magic cards can be valuable due to their rarity and utility in game play, with prices ranging from a few cents to thousands of dollars.

Deck building requires strategy as players must choose among thousands of cards which they want to play. This requires players to evaluate the power of their cards, as well as the possible synergies between them, and their possible interactions with the cards they expect to play against (this "metagame" can vary in different locations or time periods). The choice of cards is usually narrowed by the player deciding which colors they want to include in the deck. This decision is a key part of creating a deck. In general, reducing the number of colors used increases the consistency of play and the probability of drawing the lands needed to cast one's spells, at the expense of restricting the range of tactics available to the player.

Magic tournaments regularly occur in gaming stores and other venues. Larger tournaments with hundreds of competitors from around the globe sponsored by Wizards of the Coast are arranged many times every year, with substantial cash prizes for the top finishers. A number of websites report on tournament news, give complete lists for the most currently popular decks, and feature articles on current issues of debate about the game. The DCI, which is owned and operated by Wizards of the Coast, is the organizing body for sanctioned Magic events. The two major categories of tournament play are "Constructed" and "Limited".
