Each game is relatively short, but players typically will play multiple games at one sitting, sometimes until someone runs out of cards, which sometimes takes several hours. Some players form their own tournaments and many college campuses have Magic clubs, where players meet on a regular basis to duel. The rules imply that Magic is a two-player game, but several can play against each other at the same time. Terms such as enchantment, spell, sacrifice, and ogre are common to the game. There are five basic kinds of magic players use.
Black magic represents the magic of death.
Powers of the blue magician are artifice, illusion, and deception. It is mental in nature. Green magic is the magic of life. It has a peaceful exterior, but has vast destructive capability. Red magic is the magic of earth, fire, chaos, and of war.
