First, all phased-in permanents with phasing that the active player controls phase out, and all phased-out permanents that the active player controlled when they phased out phase in. This all happens simultaneously. This turn-based action doesn’t use the stack. See rule 702.26, “Phasing.”
The combat phase has five steps, which proceed in order: beginning of combat, declare attackers, declare blockers, combat damage, and end of combat. The declare blockers and combat damage steps are skipped if no creatures are declared as attackers or put onto the battlefield attacking (see rule 508.8). There are two combat damage steps if any attacking or blocking creature has first strike (see rule 702.7) or double strike (see rule 702.4).
If any of the chosen creatures have banding or a “bands with other” ability, the active player announces which creatures, if any, are banded with which. (See rule 702.22, “Banding.”)
Most abilities describe exactly what they do in the card’s rules text. Some, though, are very common or would require too much space to define on the card. In these cases, the object lists only the name of the ability as a “keyword”; sometimes reminder text summarizes the game rule.
If an effect refers to a “[keyword ability] cost,” it refers only to the variable costs for that keyword.
An effect that grants an object a keyword ability may define a variable in that ability based on characteristics of that object or other information about the game state. For these abilities, the value of that variable is constantly reevaluated.
An effect may state that “the same is true for” a list of keyword abilities or similar. If one of those keyword abilities has variants or variables and the effect grants that keyword or counters of that keyword to one or more objects and/or players, it grants each appropriate variant and variable of that keyword.
An effect may refer to an object “with [keyword ability]” or “that has [keyword ability].” This means the same thing as an object “with a [keyword ability] ability” or an object “that has a [keyword ability] ability.”
Deathtouch
Deathtouch is a static ability.
A creature with toughness greater than 0 that’s been dealt damage by a source with deathtouch since the last time state-based actions were checked is destroyed as a state-based action. See rule 704.
Any nonzero amount of combat damage assigned to a creature by a source with deathtouch is considered to be lethal damage for the purposes of determining if a proposed combat damage assignment is valid, regardless of that creature’s toughness. See rules –d.
The deathtouch rules function no matter what zone an object with deathtouch deals damage from.
If an object changes zones before an effect causes it to deal damage, its last known information is used to determine whether it had deathtouch.
Multiple instances of deathtouch on the same object are redundant.
Defender
Defender is a static ability.
A creature with defender can’t attack.
Multiple instances of defender on the same creature are redundant.
Double Strike
Double strike is a static ability that modifies the rules for the combat damage step. (See rule , “Combat Damage Step.”)
If at least one attacking or blocking creature has first strike (see rule 702.7) or double strike as the combat damage step begins, the only creatures that assign combat damage in that step are those with first strike or double strike. After that step, instead of proceeding to the end of combat step, the phase gets a second combat damage step. The only creatures that assign combat damage in that step are the remaining attackers and blockers that had neither first strike nor double strike as the first combat damage step began, as well as the remaining attackers and blockers that currently have double strike. After that step, the phase proceeds to the end of combat step.
Removing double strike from a creature during the first combat damage step will stop it from assigning combat damage in the second combat damage step.
Giving double strike to a creature with first strike after it has already dealt combat damage in the first combat damage step will allow the creature to assign combat damage in the second combat damage step.
Multiple instances of double strike on the same creature are redundant.
Enchant
Enchant is a static ability, written “Enchant [object or player].” The enchant ability restricts what an Aura spell can target and what an Aura can enchant.
For more information about Auras, see rule , “Enchantments.”
If an Aura has multiple instances of enchant, all of them apply. The Aura’s target must follow the restrictions from all the instances of enchant. The Aura can enchant only objects or players that match all of its enchant abilities.
Auras that can enchant a player can target and be attached to players. Such Auras can’t target permanents and can’t be attached to permanents.
Equip
Equip is an activated ability of Equipment cards. “Equip [cost]” means “[Cost]: Attach this permanent to target creature you control. Activate only as a sorcery.”
For more information about Equipment, see rule , “Artifacts.”
Equip abilities may further restrict what creatures may be chosen as legal targets. Such restrictions usually appear in the form “Equip [quality]” or “Equip [quality] creature.” These equip abilities may legally target only a creature that’s controlled by the player activating the ability and that has the chosen quality. Additional restrictions for an equip ability don’t restrict what the Equipment may be attached to.
If a permanent has multiple equip abilities, any of its equip abilities may be activated.
“Equip planeswalker” is a variant of the equip ability. “Equip planeswalker [cost]” means “[Cost]: Attach this permanent to target planeswalker you control as though that planeswalker were a creature. Activate only as a sorcery.”
First Strike
A creature with flying can’t be blocked except by creatures with flying and/or reach. A creature with flying can block a creature with or without flying. (See rule 509, “Declare Blockers Step,” and rule 702.17, “Reach.”)
A creature with intimidate can’t be blocked except by artifact creatures and/or creatures that share a color with it. (See rule 509, “Declare Blockers Step.”)
A creature with landwalk can’t be blocked as long as the defending player controls at least one land with the specified land type (as in “islandwalk”), with the specified type or supertype (as in “artifact landwalk”), without the specified type or supertype (as in “nonbasic landwalk”), or with both the specified type or supertype and the specified subtype (as in “snow swampwalk”). (See rule 509, “Declare Blockers Step.”)
A creature with flying can’t be blocked except by creatures with flying and/or reach. (See rule 509, “Declare Blockers Step,” and rule 702.9, “Flying.”)
If a creature with trample over planeswalkers is attacking a planeswalker and that planeswalker is removed from combat, the creature’s damage may be assigned to the defending player once all blocking creatures have been dealt lethal damage or, if there are no blocking creatures when damage is assigned, all its damage is assigned to the defending player. This is an exception to rule 506.4c, and it does not cause the creature to be attacking that player.
Attacking doesn’t cause creatures with vigilance to tap. (See rule 508, “Declare Attackers Step.”)
Rampage is a triggered ability. “Rampage N” means “Whenever this creature becomes blocked, it gets +N/+N until end of turn for each creature blocking it beyond the first.” (See rule 509, “Declare Blockers Step.”)
Flanking is a triggered ability that triggers during the declare blockers step. (See rule 509, “Declare Blockers Step.”) “Flanking” means “Whenever this creature becomes blocked by a creature without flanking, the blocking creature gets -1/-1 until end of turn.”
If a permanent phases out, its status changes to “phased out.” Except for rules and effects that specifically mention phased-out permanents, a phased-out permanent is treated as though it does not exist. It can’t affect or be affected by anything else in the game. A permanent that phases out is removed from combat. (See rule 506.4.)
A creature with shadow can’t be blocked by creatures without shadow, and a creature without shadow can’t be blocked by creatures with shadow. (See rule 509, “Declare Blockers Step.”)
A creature with horsemanship can’t be blocked by creatures without horsemanship. A creature with horsemanship can block a creature with or without horsemanship. (See rule 509, “Declare Blockers Step.”)
A creature with fear can’t be blocked except by artifact creatures and/or black creatures. (See rule 509, “Declare Blockers Step.”)
Bushido is a triggered ability. “Bushido N” means “Whenever this creature blocks or becomes blocked, it gets +N/+N until end of turn.” (See rule 509, “Declare Blockers Step.”)
A ninjutsu ability may be activated only while a creature on the battlefield is unblocked (see rule 509.1h). The creature with ninjutsu is put onto the battlefield unblocked. It will be attacking the same player, planeswalker, or battle as the creature that was returned to its owner’s hand.
Epic
Epic represents two spell abilities, one of which creates a delayed triggered ability. “Epic” means “For the rest of the game, you can’t cast spells,” and “At the beginning of each of your upkeeps for the rest of the game, copy this spell except for its epic ability. If the spell has any targets, you may choose new targets for the copy.” See rule .
A player can’t cast spells once a spell with epic they control resolves, but effects (such as the epic ability itself) can still put copies of spells onto the stack.
A creature “attacks alone” if it’s the only creature declared as an attacker in a given combat phase. See rule 506.5.
A creature with menace can’t be blocked except by two or more creatures. (See rule 509, “Declare Blockers Step.”)
A creature with skulk can’t be blocked by creatures with greater power. (See rule 509, “Declare Blockers Step.”)
Enlist’s static ability represents an optional cost to attack (see rule 508.1g). Its triggered ability is linked to that static ability (see rule ).
More Than Meets the Eye represents a static ability that functions in any zone from which the spell may be cast. “More Than Meets the Eye [cost]” means “You may cast this card converted by paying [cost] rather than its mana cost.” Casting a spell using its More Than Meets the Eye ability follows the rules for paying alternative costs (see and –h). See rule 701.50, “Convert.”
