Keywords and Keyword Abilities Reference
Magic: The Gathering encodes a staggering amount of rules complexity into single words printed on cards — words like "Flying," "Trample," or "Cascade" that expand into full rule paragraphs the moment they're invoked. This page covers the full taxonomy of keyword mechanics: what separates a keyword ability from a keyword action, how the three mechanical categories behave differently at the table, where the classification gets genuinely contested, and what players most consistently misread in tournament settings.

Definition and scope
A keyword in Magic: The Gathering is a shorthand term printed on a card that substitutes for a longer rules text the Comprehensive Rules define in full. The Magic: The Gathering Comprehensive Rules, maintained by Wizards of the Coast and updated with each major release, dedicates Section 700 and its subsections almost entirely to keyword mechanics — over 100 defined terms as of the most recent rules document.
The rules distinguish three distinct keyword categories. Keyword abilities are abilities that appear on permanents, instants, or sorceries (e.g., Flying, Lifelink, Deathtouch). Keyword actions are verbs describing game actions that aren't themselves abilities on cards (e.g., Scry, Proliferate, Mill). Ability words occupy a third lane: italicized flavor-label terms like Landfall or Adamant that group similar effects together but carry no independent rules meaning — they're essentially printed summaries, not rules triggers.
The scope matters for card types and subtypes: a creature can have 12 keyword abilities stacked on it (historically, Akroma, Angel of Wrath carried 7 at original printing), and each one is tracked, granted, and removed independently. That granularity is precisely why the shorthand system exists.
Core mechanics or structure
Keyword abilities divide further into three mechanical sub-types based on how they function:
Evergreen keywords appear across nearly every set. Wizards of the Coast designates these as format-agnostic staples — as of the current Comprehensive Rules glossary, 18 abilities carry evergreen status, including Flying, First Strike, Double Strike, Deathtouch, Lifelink, Reach, Trample, Vigilance, Haste, Flash, Hexproof, Indestructible, Menace, Prowess, and Shroud (now deprecated but still on legacy cards).
Deciduous keywords are not evergreen but appear frequently enough that players recognize them without reminder text — examples include Equip, Cycling, and Kicker. These appear in multiple sets but aren't guaranteed in every release.
Set-specific or returning keywords appear in one or a small number of sets, sometimes returning years later in a slightly modified form. Phyrexian mana symbols, Entwine, Delve, and Convoke fall here. Some, like Convoke, have been revisited in later sets after originally appearing in Ravnica block.
The mechanical behavior of a keyword ability also determines how it interacts with the stack and priority. Static keyword abilities (like Flying or Trample) don't use the stack — they define rules characteristics of a permanent and apply continuously. Triggered keyword abilities (like Lifelink, which triggers when damage is dealt, or Haunt) do resolve in a sequence that involves priority. Activated keyword abilities (like Cycling or Equip) use the stack explicitly and require a player to pay a cost.
Causal relationships or drivers
The keyword system exists because Magic's rules text space on a card is physically finite — roughly 4–8 lines depending on card layout — and Wizards has been printing sets since 1993. By the time Lorwyn released in 2007, the game had accumulated enough recurring mechanics that the design team formalized the evergreen/deciduous distinction specifically to manage rules complexity and player comprehension load.
Keywords also create what rules documents call dependency chains. Deathtouch, for instance, changes combat damage resolution: a creature with Deathtouch and Trample need only assign 1 point of combat damage to a blocker (the minimum lethal amount) before trampling excess damage to the defending player. That interaction isn't printed anywhere on either card — it's resolved entirely through the Comprehensive Rules. The combat phase breakdown page covers the damage assignment order in detail.
Keyword abilities also interact with triggered, activated, and static abilities in ways that matter enormously for timing. Lifelink, for example, was reclassified in the Magic 2010 rules update from a triggered ability to a static ability — meaning Lifelink damage and life gain now happen simultaneously rather than sequentially. That change from triggered to static altered how Lifelink interacts with replacement effects, making a 13-year-old rules interpretation obsolete overnight.
Classification boundaries
The line between a keyword ability and a non-keyword ability can be genuinely subtle. "Protection from [quality]" is a single keyword ability that encodes four separate protections (can't be damaged, enchanted/equipped, blocked, or targeted by sources of that quality) — all four effects are bundled under one word. Players who learn only that "protection means can't be targeted" are working with an incomplete ruleset.
"Hexproof" and "Shroud" are not the same classification, despite appearing similar: Hexproof prevents targeting by opponents, while Shroud prevents targeting by anyone, including the permanent's controller. Shroud was retired from evergreen status in Magic 2012 because it created usability problems — players kept trying to target their own Shroud creatures with beneficial spells, which the rules prohibit. The shift to Hexproof was a deliberate design correction.
Ability words — Landfall, Constellation, Magecraft, Raid — are sometimes mistaken for keyword abilities. They are not. An ability word has no rules meaning; the complete ability text following the italicized label is the actual game rule. Two cards can share the same ability word (Landfall) and have entirely different effects; the word is cosmetic grouping, not a mechanical trigger in itself.
Tradeoffs and tensions
Some keywords create genuine strategic tensions that make them worth evaluating carefully in deck building fundamentals. First Strike and Double Strike are not simply "better" versions of each other in all contexts: Double Strike costs significantly more mana investment (it appears on more expensive cards or requires activation), while First Strike on a small creature can be a roadblock disproportionate to its cost.
Hexproof is one of the most contested keywords from a game design perspective. The Magic: The Gathering design team, writing on DailyMTG, has discussed Hexproof's tendency to create "feel-bad" moments where an opponent's threat becomes uninteractable through targeted removal, forcing board wipes as the only answer. That tension has made Hexproof a keyword Wizards uses sparingly on creatures and almost never grants at common rarity.
Indestructible presents similar tradeoffs: it stops destruction-based removal and combat damage, but exile effects, -X/-X effects, and "sacrifice" effects bypass it entirely. A card appearing to be invincible through Indestructible is a common source of misplay and frustration for less experienced players.
Common misconceptions
Deathtouch does not give automatic kills on everything. Deathtouch causes any amount of damage dealt by that source to be lethal to a creature. It does not affect planeswalkers, players, or non-creature permanents — and it doesn't apply to non-combat damage triggered by the creature's text unless that text specifies it deals damage.
Lifelink does not "trigger." Post-Magic 2010 rules, Lifelink is a static ability. Life gain happens as part of the damage event, not after it. This matters when Lifelink damage would reduce a player to 0 life and life gain is attempted simultaneously — both events are processed in the same layer.
Flying does not make a creature unblockable. A creature with Reach can block a Flying creature. A creature with Flying can block another creature with Flying or Reach. The interaction is limited in specific ways, but "Flying = unblockable" is incorrect.
Trample does not interact with combat tricks in the way players expect. If a blocking creature gains enough toughness via an instant to survive, the attacker must assign lethal damage to it before trampling — the recalculation happens based on the creature's toughness at the time damage is assigned, not when blockers were declared.
