The core game follows the standard rules of the collectible card game Magic: The Gathering; each player has a deck of cards consisting of lands and spells. Lands are used to generate "mana," the resource needed to cast spells. Mana comes in five colors, and cards may require colored or generic (mana of any color) to be cast. Spells come in many varieties, from sorceries which have a one-time effect, to summoned creatures which can attack and defend from opponents. Players alternate turns playing land cards, casting spells, and attacking opponents until all but one player's life total is reduced to 0. Unlike the paper cardgame, you cannot make your deck of cards in the videogame.
