Mana Symbol

The mana symbols are {W}, {U}, {B}, {R}, {G}, {X}, {Y}, {Z} and the numerals {0}, {1}, {2}, {3}, {4}, and so on, and the hybrid symbols {W/U}, {W/B}, {U/B}, {U/R}, {B/R}, {B/G}, {R/G}, {R/W}, {G/W}, and {G/U}. See rule 104.3. Each of the colored mana symbols represents one colored mana: {W} white, {U} blue, {B} black, {R} red, and {G} green. See rule 104.3a. Numeral symbols (such as {1}) are generic mana costs and represent an amount of mana that can be paid with any color of, or colorless, mana. See rule 104.3b. The symbols {X}, {Y} and {Z} represent unspecified amounts of mana; when playing a spell or activated ability with {X}, {Y}, or {Z} in its cost, its controller decides the value of that variable. See rule 104.3c. Numeral symbols and variable symbols can also represent colorless mana if they appear in the effect of a spell or of a mana ability that reads "add [mana symbol] to your mana pool" or something similar. See rule 104.3d. The symbol {0} represents zero mana and is used as a placeholder when a spell or activated ability costs nothing to play. A spell or ability whose cost is {0} must still be played the same way as one with a cost greater than zero; it won't play itself automatically. See rule 104.3e. Each of the hybrid mana symbols represents a cost which can be paid with one of two colors: {W/U} in a cost can be paid with either white or blue mana, {W/B} white or black, {U/B} blue or black, {U/R} blue or red, {B/R} black or red, {B/G} black or green, {R/G} red or green, {R/W} red or white, {G/W} green or white, and {G/U} green or blue. See rule 104.3f.
