502.30b If a spell has multiple instances of storm, each triggers separately.
502.31. Affinity
502.31a Affinity is a static ability that functions while the spell is on the stack. “Affinity for [text]” means “This spell costs you {1} less to play for each [text] you control.”
502.31b The affinity ability reduces only generic mana costs; it doesn’t reduce how much colored mana you have to pay for a spell. Affinity can’t reduce the cost to play a spell to less than 0.
502.31c If a spell has multiple instances of affinity, each of them applies.
502.32. Entwine
502.32a Entwine is a static ability that functions while the spell is on the stack. “Entwine [cost]” means “You may choose to use all modes of this spell instead of just one. If you do, you pay an additional [cost].” Using the entwine ability follows the rules for choosing modes and paying additional costs in rules 409.1b and 409.1f-h.
502.32b 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.
502.33. Equip
502.33a Equip is an activated ability of artifact Equipment cards. “Equip [cost]” means “[Cost]: Attach this Equipment to target creature you control. Play this ability only any time you could play a sorcery.”
502.33b For more information about Equipment, see rule 212.2, “Artifacts.”
502.33c If an artifact has multiple instances of equip, any of its equip abilities may be used.
502.34. Imprint
502.34a Imprint is an activated or triggered ability, written “Imprint – [text],” where “[text]” is a triggered or activated ability. Cards that are in the removed-from-the-game zone because they were removed from the game by an imprint ability are imprinted on the source of that ability.
502.34b The phrase “imprinted [type] card” means the card of that type that’s imprinted on the permanent. If a permanent has more than one card of that type imprinted on it, each of those cards is an “imprinted [type] card.”
502.35. Modular
502.35a Modular represents both a static ability and a triggered ability. “Modular N” means “This permanent comes into play with N +1/+1 counters on it” and “When this permanent is put into a graveyard from play, you may put a +1/+1 counter on target artifact creature for each +1/+1 counter on this permanent.”
502.35b If a creature has multiple instances of modular, each one works separately.
502.36. Scry
502.36a Scry is a static ability that functions while a spell or ability is resolving. “Scry N” means “Look at the top N cards of your library. Put any number of them on the bottom of your library in any order and the rest on top of your library in any order.”
502.36b If a spell or ability has multiple instances of scry, each one works separately.
502.37. Sunburst
502.37a Sunburst is a static ability that functions as an object is coming into play from the stack. “Sunburst” means “If this object is coming into play from the stack as a creature, it comes into play with a +1/+1 counter on it for each color of mana used to pay its cost. If this object is coming into play from the stack and isn’t coming into play as a creature, it comes into play with a charge counter on it for each color of mana used to pay its cost.”
502.37b Sunburst applies only as the spell is resolving and only if one or more colored mana was paid for its costs. Mana paid for additional or alternative costs applies.
502.37c 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.
Example: The ability “Modular-Sunburst” means “This permanent comes into play with a +1/+1 counter on it for each color of mana used to pay its cost” and “When this permanent is put into a graveyard from play, you may put a +1/+1 counter on target artifact creature for each +1/+1 counter on this permanent.”
502.37d If an object has multiple instances of sunburst, each one works separately.
502.38. Bushido
502.38a 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 309, “Declare Blockers Step.”)
502.38b If a creature has multiple instances of bushido, each triggers separately.
502.39. Soulshift
502.39a Soulshift is a triggered ability. “Soulshift N” means “When this permanent is put into a graveyard from play, you may return target Spirit card with converted mana cost N or less from your graveyard to your hand.”
502.39b If a permanent has multiple instances of soulshift, each triggers separately.
502.40. Splice
502.40a Splice is a static ability that functions while a card is in your hand. “Splice onto [type or subtype] [cost]” means “You may reveal this card from your hand as you play a [type or subtype] spell. If you do, copy this card’s text box onto that spell and pay [cost] as an additional cost to play that spell.” Paying a card’s splice cost follows the rules for paying additional costs in rules 409.1b and 409.1f-h.
Example: Since the card with splice remains in the player’s hand, it can later be played normally or spliced onto another spell. It can even be discarded to pay a “discard a card” cost of the spell it’s spliced onto.
502.40b You can’t choose to use a splice ability if you can’t make the required choices (targets, etc.) for that card’s instructions. 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 instructions will be followed. The instructions on the main spell have to be followed first.
502.40c The spell has the characteristics of the main spell, plus the text boxes of each of the spliced cards. The spell doesn’t gain any other characteristics (name, mana cost, color, supertypes, types, subtypes, etc.) of the spliced cards. Text copied onto 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.
Example: Glacial Ray is a red card with splice onto Arcane that reads, “Glacial Ray deals 2 damage to target creature or player.” Suppose Glacial Ray is spliced onto Reach Through Mists, a blue spell. The spell is still blue, and Reach Through Mists deals the damage. This means that the ability can target a creature with protection from red and deal 2 damage to that creature.
