104 - Numbers and Symbols
- 104.1 - The Magic game uses only integers. [CompRules 2007/05/01]
- 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. [CompRules 2007/05/01]
- 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.
[CompRules 2007/05/01]
Example: 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. [CompRules 2007/05/01]
Example: Viridian Joiner is a 1/2 creature that says "{Tap}: Add an
amount of {G} 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. [CompRules 2007/05/01]
- 104.2 - If anything needs to use a number that can't be determined, either
as a result or in a calculation, it uses 0 instead. [CompRules 2007/05/01]
- 104.3 - The mana symbols are {W}, {U}, {B}, {R}, {G}, and {X}; the
numerals {0}, {1}, {2}, {3}, {4}, and so on; the bybrid symbols {W/U},
{W/B}, {U/B}, {U/R}, {B/R}, {B/G}, {R/G}, {R/W}, {G/W}, and {G/U}; and
the snow symbol {S}. [CompRules 2007/10/01]
- 104.3a - Each of the colored mana symbols represents one colored mana: {W}
is white, {U} blue, {B} black, {R} red, and {G} green.
[CompRules 2003/07/01]
- 104.3b - 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.
[CompRules 2003/07/01]
- 104.3c - The symbol {X} represents an unspecified amount of mana. When
playing a spell or activated ability with {X} in its cost, its controller
decides the value of that variable. [CompRules 2007/10/01]
- 104.3d - Numeral symbols (such as {1}) and variable symbols (such as {X})
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. [CompRules 2003/07/01]
- 104.3e - 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.
[CompRules 2003/07/01]
- 104.3f - Each of the hybrid mana symbols represents a cost that 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. A hybrid
mana systmbol is each of its component colors.
[CompRules 2007/05/01]
Example: {G/W}{G/W} can be paid by spending {G}{G}, {G}{W}, or {W}{W}.
[CompRules 2005/10/01]
- 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.
[CompRules 2006/07/15]
- 104.3h - The snow mana symbol {S} 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 {S} costs.
[CompRules 2006/07/15]
- 104.4 - The tap symbol is {Tap}. 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. [CompRules 2003/07/01]
- 104.5 - A tombstone icon appears to the left of the name of many
Odyssey(tm) 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.
[CompRules 2003/07/01]
- 104.6 - A type icon appears in the upper left corner of each card from the
Future Sight(tm) 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.
[CompRules 2007/07/13]
- 104.7 - Each activated ability of a planeswalker has an arrow-shaped loyalty
symbol in its cost. Positive loyalty symbols point upward and feature a
plus sign followed by a number or an X. Negative loyalty symbols point
downward and feature a minus sign followed by a number or an X. [+N]
means "Put N loyalty counters on this permanent," and [-N] means "Remove N
loyalty counters from this permanent." [CompRules 2007/10/01]
