Creature pumping

Creature pumping is a slang term used by Magic R&D to describe spells or abilities that modify the power and/or toughness of creatures. Each color has its own way to this.
==+N/+N==
===White===
White's pumping by both instants and auras are usually +2/+2 or smaller, often granting an ability as well. The one exception for white is that it can get larger pumps if the effect is restricted to blockers, or requires counting of resources (Plains or creatures). Some very lopsided toughness pumps (i.e. <c>Aegis of the Heavens</c>) fall into the design space of +N/+0 and "prevent all damage". 
===Blue===
Blue's auras are small pump effects per mana spent, with flying being the most common ability granted. Blue doesn't usually get instants to do this, relying on transformation stat-changing to do this. It has started getting temporary evasion spells that boost power and toughness as a surprise way to end games.
===Black===
Black is primary in straightforward pumping by activation costs on creatures. This is mostly seen on Shades and usually requires black mana. Black will occasionally get smaller buffs by instants, usually with an ability added. Black auras are not usually in this category; those that are give small boosts.
===Red===
Red has several cheap Auras that give +2/+2 and something else, either a small bonus at more expensive costs or a drawback at cheaper costs. Red's instants normally give low toughness boosts that make it hard to save the creature defensively, though aggressively they have higher toughness boosts ().
===Green===
Green is secondary in straightforward pumping by activation costs on creatures. These often are unlimited but usually only when the activation cost is high enough that multiple activations don't happen until the late game. Green is primary in one-off pumping, the almost-exclusive <c>Rootwalla</c> ability. Green's instants are the best on rate, like the iconic <c>Giant Growth</c>, and generally the only color to give +4/+4 or higher. Smaller pumps are used with fight spells, letting smaller creatures fight on-curve more often. Green is the one color that regularly grants +3/+3 and above on auras, but rarely gives other abilities. Green has the most "flash auras" or the like, giving sizable and permanent pumps at instant speed.
==+N/+0==
===On creatures===
This ability, as a repeatable activation, is what is referred to as "firebreathing." It's primarily seen on red creatures. White and green tends to get one-time upgrades of usually +1/+0, as a way to push smaller creatures in against larger blockers. 
===On spells===
Black and red are the two colors that tend to pump power as a spell without also pumping toughness. To make them useful in combat, Black either regenerates, grants indestructible, or something similar, while Red grants first or double strike. White does it occasionally as a combat trick but usually never more than +2/+0; both white and red share the "<c>Trumpet Blast</c>" effect, with white granting toughness at higher costs.
===On auras===
As Auras are already a significant liability, no-toughness auras are often a hard sell, so this category is sparse in modern design. Red is the color most often to have just power-pumping Auras (including "firebreathing" Auras). White and black did it occasionally with white tending to go no higher than +2/+0. Blue and green do it on even more rare occasions with blue, like white, sticking at +2/+0 or lower. 
==+N/-N==
===On creatures===
Black and Red use this on occasion to play up their reckless side. Blue once used this on Elementals and Shapeshifters but now has returned to having it on any sort of creature; while once abandoned due to the aggressive potential, it has returned on average creatures with higher toughness to give them some commons better combat potential.
===On spells===
As this is mostly used as a kill spell, the ability resides mostly in black.
===On auras===
These tend to be flavored as "push your luck" cards that can double as creature kill. Black will go up to -3 on the toughness, whereas red tends to stop at -2. Blue used to have some "make me a shapeshifter" flavored Auras, but has moved away from that.
==-N/+N==
===On Creatures===
This is also used in blue on Elementals and Shapeshifters, often on the same cards with the +N/-N. White, on rare occasions, will have an activation that uses this defensively. Largely phased out by R&D because it tends to just clog up the board; few instants or Auras perform this effect nowadays.
==-N/-N==
Almost entirely relegated to black creature removal, few creatures inflict this on themselves. Black gets this in many forms; some are small or inefficient enough to act only as combat tricks, but others are large enough to count as direct kill spells.
==-N/-0==
In blue, this is shrinking its target. Instants typically are paired with some form of scry effect or cantrip due to the low impact; blue Auras are quasi-removal effects, with all the associated downsides attached. However, an unintended combo can happen with power/toughness switcher effects, like , that can give blue a graveyard-sending removal it's not supposed to have; switching has become extremely rare as a consequence.
In black it's usually some form of torture. With all its creature interaction, it tends to not need it as a spell or aura. Four creatures give themselves -N/-0 in exchange for some form of evasion.
==+0/+N== 
White used to do this quite a bit, but like -N/+N it is less used. It is now used to enable small-creature attackers by invalidating low-power blockers. Green also uses this on occasion with the same design intent, and some number of reach-granting instants give no power, and finally, one fight card gives only toughness rather than also power (<c>Warbriar Blessing</c>). Blue uses it, sometimes with hexproof, on protective spells.
==Team pumping==
White is the color most likely to pump its team, most often with +1/+1, but it will occasionally go up to +2/+2. Green's team pump starts at +2/+2 and often also adds trample. Team pump that only pumps power is most often done in red, usually affecting attacking creatures.
