414.2. The player who played the countered spell or ability doesn’t get a “refund” of any costs that were paid.
415.1. An instant or sorcery spell is targeted if the text that will be followed when it resolves uses the phrase “target [something],” where the “something” is a phrase that describes an object, player, or zone. (If an activated or triggered ability of an instant or sorcery uses the word target, that ability is targeted, but the spell is not.)
Example: A sorcery card has the ability “When you cycle this card, target creature gets -1/-1 until end of turn.” This triggered ability is targeted, but that doesn’t make the card it’s on targeted.
415.2. An activated or triggered ability is targeted if it uses the phrase “target [something],” where the “something” is a phrase that describes an object, player, or zone.
415.3. Aura spells are always targeted. An Aura’s target is specified by its enchant keyword ability (see rule 502.45, “Enchant”). An Aura permanent doesn’t target anything; only the spell is targeted. An activated or triggered ability of an Aura permanent can be targeted.
Neither Equipment spells nor Equipment permanents target anything. The equip ability is targeted; see rule 502.33, “Equip.” An activated or triggered ability of an Equipment permanent can be targeted.
415.4. Spells and abilities that can have zero or more targets are targeted only if one or more targets have been chosen for them.
415.5. Only permanents are legal targets for spells and abilities, unless a spell or ability (a) specifies that it can target an object in another zone or a player or (b) targets an object that can’t exist in the in-play zone, such as a spell or ability.
415.6. A spell or ability on the stack is an illegal target for itself.
415.7. Changing Targets
415.7a The target of a spell or ability can change only to another legal target. If the target can’t be changed to another legal target, the original target is unchanged.
415.7b Modal spells and abilities may have different targeting requirements for each mode. Changing a spell or ability’s target can’t change its mode.
415.7c The word “you” in an object’s text isn’t a target.
416.1. When a spell or ability resolves, it may create one or more one-shot or continuous effects. Static abilities may create one or more continuous effects. Some effects are replacement effects or prevention effects. State-based effects are not created by spells or abilities; they are generated by specific rules of the game.
416.2. Effects apply only to permanents unless the instruction’s text states otherwise or they clearly can apply only to objects in one or more other zones.
Example: An effect that changes all lands into creatures won’t alter land cards in players’ graveyards. But an effect that says spells cost more to play will apply only to spells on the stack, since a spell is always on the stack while you are playing it.
416.3. If an effect attempts to do something impossible, it does only as much as possible.
Example: If a player is holding only one card, an effect that reads “Discard two cards” causes him or her to discard only that card. If an effect moves cards out of the library (as opposed to drawing), it moves as many as possible.
417.1. A one-shot effect does something just once and doesn’t have a duration. Examples include damage dealing, destruction of permanents, and moving objects between zones.
417.2. Some one-shot effects instruct a player to do something later in the game (usually at a specific time) rather than when they resolve. This kind of effect actually creates a new ability that waits to be triggered. (See rule 404.4.)
418.1. A continuous effect modifies characteristics of objects or modifies the rules of the game for a fixed or indefinite period. A continuous effect may be generated by the resolution of a spell or ability or by a static ability of an object.
418.2. Continuous effects that modify characteristics of permanents do so simultaneously with the permanent coming into play. They don’t wait until the permanent is in play and then change it. Because such effects apply as the permanent comes into play, apply them before determining whether the permanent will cause an ability to trigger when it comes into play.
418.3. Continuous Effects from Spells or Abilities
418.3a A continuous effect generated by the resolution of a spell or ability lasts as long as stated by the spell or ability creating it (such as “until end of turn”). If no duration is stated, it lasts until the end of the game.
418.3b Continuous effects from spells, activated abilities, and triggered abilities that modify the characteristics or change the controller of one or more objects don’t affect objects that weren’t affected when the continuous effect began. Note that these work differently than continuous effects from static abilities. Continuous effects that don’t modify characteristics or change the controller of objects modify the rules of the game, so they can affect objects that weren’t affected when the continuous effect began.
Example: An effect that reads “All white creatures get +1/+1 until end of turn” gives the bonus to all permanents that are white creatures when the spell or ability resolves-even if they change color later-and doesn’t affect those that come into play or turn white afterward.
Example: An effect that reads “Prevent all damage creatures would deal this turn” doesn’t modify any object’s characteristics, so it’s modifying the rules of the game. That means the effect will apply even to damage from creatures that weren’t in play when the continuous effect began. It also affects damage from permanents that become creatures later in the turn.
418.3c If a resolving spell or ability that creates a continuous effect contains a variable, the value of that variable is determined only once, on resolution. See rule 413.2f.
418.3d Some effects from activated or triggered abilities have durations worded “as long as . . . .” If the “as long as” duration ends between the end of playing the activated ability or putting the triggered ability onto the stack and the moment when the effect would first be applied, the effect does nothing. It doesn’t start and immediately stop again, and it doesn’t last forever.
Example: Endoskeleton is an artifact with an activated ability that reads “{2}, {T}: Target creature gets +0/+3 as long as Endoskeleton remains tapped.” If you play this ability and then Endoskeleton becomes untapped before the ability resolves, it does nothing, because its duration-remaining tapped-was over before the effect began.
