Comprehensive Rules

Some enchantments have the subtype “Aura.” An Aura enters the battlefield attached to an object or player. What an Aura can be attached to is defined by its enchant keyword ability (see rule 702.5, “Enchant”). Other effects can limit what a permanent can be enchanted by.

After resolving a madness triggered ability (see rule 702.35), if the exiled card wasn’t cast and was moved to a public zone, effects referencing the discarded card can find that object.

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 at least one attacking or blocking creature has first strike (see rule 702.7) or double strike (see rule 702.4) 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.

If the spell is modal, the player announces the mode choice (see rule 700.2). If the player wishes to splice any cards onto the spell (see rule 702.47), they reveal those cards in their hand. If the spell has alternative or additional costs that will be paid as it’s being cast such as buyback or kicker costs (see rules 118.8 and 118.9), the player announces their intentions to pay any or all of those costs (see rule 601.2f). A player can’t apply two alternative methods of casting or two alternative costs to a single spell. If the spell has a variable cost that will be paid as it’s being cast (such as an {X} in its mana cost; see rule 107.3), the player announces the value of that variable. If the value of that variable is defined in the text of the spell by a choice that player would make later in the announcement or resolution of the spell, that player makes that choice at this time instead of that later time. If a cost that will be paid as the spell is being cast includes hybrid mana symbols, the player announces the nonhybrid equivalent cost they intend to pay. If a cost that will be paid as the spell is being cast includes Phyrexian mana symbols, the player announces whether they intend to pay 2 life or a corresponding colored mana cost for each of those symbols. Previously made choices (such as choosing to cast a spell with flashback from a graveyard or choosing to cast a creature with morph face down) may restrict the player’s options when making these choices.

A splice ability changes a spell’s text by adding the rules text of the card with splice to the spell, following that spell’s own rules text. It doesn’t modify or replace any of that spell’s own text. (See rule 702.47, “Splice.”)

Double Strike

Double strike is a static ability that modifies the rules for the combat damage step. (See rule 510, “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.

If at least one attacking or blocking creature has first strike or double strike (see rule 702.4) 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.

Phased-out permanents owned by a player who leaves the game also leave the game. This doesn’t cause zone-change abilities to trigger. See rule 800.4.

In a multiplayer game, game rules may cause a phased-out permanent to leave the game or to be exiled once a player leaves the game. (See rules 800.4a and 800.4c.) If a phased-out permanent phased out under the control of a player who has left the game, that permanent phases in during the next untap step after that player’s next turn would have begun.

Storm

Storm is a triggered ability that functions on the stack. “Storm” means “When you cast this spell, copy it for each other spell that was cast before it this turn. If the spell has any targets, you may choose new targets for any of the copies.”

If a spell has multiple instances of storm, each triggers separately.

Affinity

Affinity is a static ability that functions while the spell with affinity is on the stack. “Affinity for [text]” means “This spell costs you {1} less to cast for each [text] you control.”

If a spell has multiple instances of affinity, each of them applies.

Entwine

Entwine is a static ability of modal spells (see rule 700.2) that functions while the spell is on the stack. “Entwine [cost]” means “You may choose all modes of this spell instead of just the number specified. If you do, you pay an additional [cost].” Using the entwine ability follows the rules for choosing modes and paying additional costs in rules 601.2b and 601.2f–h.

If the entwine cost was paid, follow the text of each of the modes in the order written on the card when the spell resolves.

Modular

Modular represents both a static ability and a triggered ability. “Modular N” means “This permanent enters with N +1/+1 counters on it” and “When this permanent is put into a graveyard from the battlefield, you may put a +1/+1 counter on target artifact creature for each +1/+1 counter on this permanent.”

If a creature has multiple instances of modular, each one works separately.

Sunburst

Sunburst is a static ability that functions as an object is entering the battlefield. “Sunburst” means “If this object is entering as a creature, ignoring any type-changing effects that would affect it, it enters with a +1/+1 counter on it for each color of mana spent to cast it. Otherwise, it enters with a charge counter on it for each color of mana spent to cast it.”

Sunburst adds counters only if the object with sunburst is entering the battlefield from the stack as a resolving spell and only if one or more colored mana was spent on its costs, including additional or alternative costs.

Sunburst can also be used to set a variable number for another ability. If the keyword is used in this way, it doesn’t matter whether the ability is on a creature spell or on a noncreature spell.

If an object has multiple instances of sunburst, each one works separately.

Bushido

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.”)

If a creature has multiple instances of bushido, each triggers separately.

Soulshift

Soulshift is a triggered ability. “Soulshift N” means “When this permanent is put into a graveyard from the battlefield, you may return target Spirit card with mana value N or less from your graveyard to your hand.”

If a permanent has multiple instances of soulshift, each triggers separately.

Splice

Splice is a static ability that functions while a card is in your hand. “Splice onto [quality] [cost]” means “You may reveal this card from your hand as you cast a [quality] spell. If you do, that spell gains the text of this card’s rules text and you pay [cost] as an additional cost to cast that spell.” Paying a card’s splice cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

You can’t choose to use a splice ability if you can’t make the required choices (targets, etc.) for that card’s rules text. You can’t splice any one card onto the same spell more than once. If you’re splicing more than one card onto a spell, reveal them all at once and choose the order in which their effects will happen. The effects of the main spell must happen first.

The spell has the characteristics of the main spell, plus the rules text of each of the spliced cards. This is a text-changing effect (see rule 612, “Text-Changing Effects”). The spell doesn’t gain any other characteristics (name, mana cost, color, supertypes, card types, subtypes, etc.) of the spliced cards. Text gained by the spell that refers to a card by name refers to the spell on the stack, not the card from which the text was copied.

Choose targets for the added text normally (see rule 601.2c). Note that a spell with one or more targets won’t resolve if all of its targets are illegal on resolution.

The spell loses any splice changes once it leaves the stack for any reason.

Offering

Offering is a static ability that functions while the spell with offering is on the stack. “[Quality] offering” means “As an additional cost to cast this spell, you may sacrifice a [quality] permanent. If you chose to pay the additional cost, this spell’s total cost is reduced by the sacrificed permanent’s mana cost, and you may cast this spell any time you could cast an instant.”

You choose which permanent to sacrifice as you make choices for the spell (see rule 601.2b), and you sacrifice that permanent as you pay the total cost (see rule 601.2h).

Generic mana in the sacrificed permanent’s mana cost reduces generic mana in the spell’s total cost. Colored and colorless mana in the sacrificed permanent’s mana cost reduces mana of the same type in spell’s total cost, and any excess reduces that much generic mana in spell’s total cost. (See rule 118.7.)

Ninjutsu

Ninjutsu is an activated ability that functions only while the card with ninjutsu is in a player’s hand. “Ninjutsu [cost]” means “[Cost], Reveal this card from your hand, Return an unblocked attacking creature you control to its owner’s hand: Put this card onto the battlefield from your hand tapped and attacking.”

The card with ninjutsu remains revealed from the time the ability is announced until the ability leaves the stack.

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.

Commander ninjutsu is a variant of the ninjutsu ability that also functions while the card with commander ninjutsu is in the command zone. “Commander ninjutsu [cost]” means “[Cost], Reveal this card from your hand or from the command zone, Return an unblocked attacking creature you control to its owner’s hand: Put this card onto the battlefield tapped and attacking.”

A fused split spell has the combined characteristics of its two halves. (See rule 709.4.)

If a creature has multiple instances of renown, each triggers separately. The first such ability to resolve will cause the creature to become renowned, and subsequent abilities will have no effect. (See rule 603.4)

A rule or effect that refers to your commander’s color identity refers to the combined color identities of your two commanders. See rule 903.4.

A max speed ability is a special kind of static ability. “Max speed — [Ability]” means “As long as your speed is 4, this object has ‘[Ability].’” See rule 702.179, “Start Your Engines!”

Rules and effects may refer to whether a player has “max speed.” A player has max speed if their speed is 4.

The characteristics of a fused split spell on the stack are also those of its two halves combined (see rule 702.102, “Fuse”).

Any ability a leveler card has that isn’t preceded by a level symbol is treated normally. In particular, each leveler permanent has its level up ability (see rule 702.87) at all times; it may be activated regardless of how many level counters are on that permanent.
