***104.1a You can’t choose a fractional number, deal fractional damage, gain fractional life, and so on. If a spell or ability could generate a fractional number, the spell or ability will tell you whether to round up or down. | ***'''104.1a''' You can’t choose a fractional number, deal fractional damage, gain fractional life, and so on. If a spell or ability could generate a fractional number, the spell or ability will tell you whether to round up or down. | ||
***104.1b Most of the time, the Magic game uses only positive numbers. You can’t choose a negative number, deal negative damage, gain negative life, and so on. However, it’s possible for a game value, such as a creature’s power, to be less than zero. If a calculation or comparison that would determine the result of an effect needs to use a negative value, it does so. If such a calculation yields a negative number, zero is used instead, unless that effect sets a creature’s power or toughness, changes a creature’s power or toughness, or sets a player’s life total.<br> | ***'''104.1b''' Most of the time, the Magic game uses only positive numbers.

'''Example''':<br> If a 3/4 creature gets -5/-0, it’s a -2/4 creature. It deals no damage in combat. Its total power and toughness is 2. You’d have to give it +3/+0 to raise its power to 1.<br> | ***'''Example''':<br> If a 3/4 creature gets -5/-0, it’s a -2/4 creature. It deals no damage in combat. Its total power and toughness is 2.

'''Example''':<br> <c>Viridian Joiner</c> is a 1/2 creature that says “{T}: Add an amount of [[image:Manag.gif]] to your mana pool equal to Viridian Joiner’s power.” An effect gives it -2/-0, then its ability is activated. The ability adds no mana to your mana pool. | ***'''Example''':<br> <c>Viridian Joiner</c> is a 1/2 creature that says “{T}: Add an amount of [[image:Manag.gif]] to your mana pool equal to Viridian Joiner’s power.” An effect gives it -2/-0, then its ability is activated.

**104.3. The mana symbols are [[image:Manaw.gif]], [[image:Manau.gif]], [[image:Manab.gif]], [[image:Manar.gif]], [[image:Manag.gif]], and [[image:Manax.gif]]; the numerals [[image:Mana0.gif]], [[image:Mana1.gif]], [[image:Mana2.gif]], [[image:Mana3.gif]], [[image:Mana4.gif]], and so on; the hybrid symbols [[image:Manauw.gif]], [[image:Manawb.gif]], [[image:Manaub.gif]], [[image:Manaur.gif]], [[image:Manarb.gif]], [[image:Managb.gif]], [[image:Managr.gif]], [[image:Manarw.gif]], [[image:Manawg.gif]], and [[image:Manaug.gif]]; and the snow symbol [[image:Manas.gif]]. | **'''104.3.''' The mana symbols are [[image:Manaw.gif]], [[image:Manau.gif]], [[image:Manab.gif]], [[image:Manar.gif]], [[image:Manag.gif]], and [[image:Manax.gif]]; the numerals [[image:Mana0.gif]], [[image:Mana1.gif]], [[image:Mana2.gif]], [[image:Mana3.gif]], [[image:Mana4.gif]], and so on; the hybrid symbols [[image:Manauw.gif]], [[image:Manawb.gif]], [[image:Manaub.gif]], [[image:Manaur.gif]], [[image:Manarb.gif]], [[image:Managb.gif]], [[image:Managr.gif]], [[image:Manarw.gif]], [[image:Manawg.gif]], and [[image:Manaug.gif]]; and the snow symbol [[image:Manas.gif]]. | ||
***104.3a Each of the colored mana symbols represents one colored mana: [[image:Manaw.gif]] is white, [[image:Manau.gif]] blue, [[image:Manab.gif]] black, [[image:Manar.gif]] red, and [[image:Manag.gif]] green. | ***'''104.3a''' Each of the colored mana symbols represents one colored mana: [[image:Manaw.gif]] is white, [[image:Manau.gif]] blue, [[image:Manab.gif]] black, [[image:Manar.gif]] red, and [[image:Manag.gif]] green. | ||
***104.3b Numeral symbols (such as [[image:Mana1.gif]]) are generic mana costs and represent an amount of mana that can be paid with any color of, or colorless, mana. | ***'''104.3b''' Numeral symbols (such as [[image:Mana1.gif]]) are generic mana costs and represent an amount of mana that can be paid with any color of, or colorless, mana. | ||
***104.3c The symbol [[image:Manax.gif]] represents an unspecified amount of mana; when playing a spell or activated ability with [[image:Manax.gif]] in its cost, its controller decides the value of that variable. | ***'''104.3c''' The symbol [[image:Manax.gif]] represents an unspecified amount of mana; when playing a spell or activated ability with [[image:Manax.gif]] in its cost, its controller decides the value of that variable. | ||
***104.3d Numeral symbols (such as [[image:Mana1.gif]]) and variable symbols (such as [[image:Manax.gif]]) can also represent colorless mana if they appear in the effect of a spell or ability that reads “add [mana symbol] to your mana pool” or something similar. | ***'''104.3d''' Numeral symbols (such as [[image:Mana1.gif]]) and variable symbols (such as [[image:Manax.gif]]) can also represent colorless mana if they appear in the effect of a spell or ability that reads “add [mana symbol] to your mana pool” or something similar. | ||
***104.3e The symbol [[image:Mana0.gif]] 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 [[image:Mana0.gif]] must still be played the same way as one with a cost greater than zero; it won’t play itself automatically. | ***'''104.3e''' The symbol [[image:Mana0.gif]] 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 [[image:Mana0.gif]] must still be played the same way as one with a cost greater than zero; it won’t play itself automatically. | ||
***104.3f Each of the hybrid mana symbols represents a cost that can be paid with one of two colors: [[image:Manauw.gif]] in a cost can be paid with either white or blue mana, [[image:Manawb.gif]] white or black, [[image:Manaub.gif]] blue or black, [[image:Manaur.gif]] blue or red, [[image:Manarb.gif]] black or red, [[image:Managb.gif]] black or green, [[image:Managr.gif]] red or green, [[image:Manarw.gif]] red or white, [[image:Managw.gif]] green or white, and [[image:Managu.gif]] green or blue.

A hybrid mana symbol is each of its component colors.<br> | ||
Example: [[image:Managw.gif]][[image:Managw.gif]] can be paid by spending [[image:Manag.gif]][[image:Manag.gif]], [[image:Manag.gif]][[image:Manaw.gif]], or [[image:Manaw.gif]][[image:Manaw.gif]]. | ***Example:<br> [[image:Managw.gif]][[image:Managw.gif]] can be paid by spending [[image:Manag.gif]][[image:Manag.gif]], [[image:Manag.gif]][[image:Manaw.gif]], or [[image:Manaw.gif]][[image:Manaw.gif]]. | ||
***104.3g If an effect would add one mana represented by a hybrid mana symbol to a player’s mana pool, that player chooses either of that symbol’s colors and adds one mana of that color to his or her mana pool. | ***'''104.3g''' If an effect would add one mana represented by a hybrid mana symbol to a player’s mana pool, that player chooses either of that symbol’s colors and adds one mana of that color to his or her mana pool. | ||
***104.3h The snow mana symbol [[image:Manas.gif]] represents a cost that can be paid with one mana produced by a snow permanent. This is a generic mana cost that can be paid with any color of, or colorless, mana. Effects that reduce the amount of generic mana you pay don’t affect [[image:Manas.gif]] costs. | ***'''104.3h''' The snow mana symbol [[image:Manas.gif]] represents a cost that can be paid with one mana produced by a snow permanent. This is a generic mana cost that can be paid with any color of, or colorless, mana. Effects that reduce the amount of generic mana you pay don’t affect [[image:Manas.gif]] costs. | ||
**104.4. The tap symbol is {T}. The tap symbol in an activation cost means “Tap this permanent.” A permanent that’s already tapped can’t be tapped again to pay the cost. Creatures that haven’t been under a player’s control continuously since the beginning of his or her most recent turn can’t use any ability with the tap symbol in the cost. See rule 212.3f. | **'''104.4.''' The tap symbol is {T}. The tap symbol in an activation cost means “Tap this permanent.” A permanent that’s already tapped can’t be tapped again to pay the cost.

**104.5. A tombstone icon appears to the left of the name of many [[Odyssey (block)|Odyssey block]] cards with abilities that are relevant in a player’s graveyard. The purpose of the icon is to make those cards stand out when they’re in a graveyard. This icon has no effect on game play. | **'''104.5.'''

**104.6. A type icon appears in the upper left corner of each card from the [[Future Sight]] set printed with an alternate “timeshifted” frame. If the card has a single card type, this icon indicates what it is: claw marks for creature, a flame for sorcery, a lightning bolt for instant, a sunrise for enchantment, a chalice for artifact, and a pair of mountain peaks for land. If the card has multiple card types, that’s indicated by a black and white cross. This icon has no effect on game play. | **'''104.6.'''
