In the CCG Magic: The Gathering mana is magical power, usually gathered from the land, though some various objects, spells and creatures can summon its power (Elves, sacrificial rituals, and certain artifacts). Mana is gathered by tapping the lifeforce of the land, which drains it for a short time (1 game turn). If the mana is not used within the turn, it begins to tear apart the body of the person who is trying to hold it, causing mana burn, an harmful inner fire. This is easily avoided by only gathering enough mana to cast the spells needed.

Mana is used by super-human creatures called planeswalkers to power their spells, and the abilities of their minions. It is most commonly used in duels between two or more planeswalkers. These duels are the subject of this game.
