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.

502.40d Choose targets for the added text normally (see rule 409.1c). Note that a spell with one or more targets will be countered if all of its targets are illegal on resolution.

502.40e The spell loses any splice changes once it leaves the stack (for example, when it’s countered, it’s removed from the game, or it resolves).

502.41. Defender

502.41a Defender is a static ability.

502.41b A creature with defender can’t attack.

502.41c Multiple instances of defender on the same creature are redundant.

502.42. Offering

502.42a Offering is a static ability of a card that functions in any zone from which the card can be played. “[Text] offering” means “You may play this card any time you could play an instant by sacrificing a [text] permanent. If you do, the total cost to play this card is reduced by the sacrificed permanent’s mana cost.”

502.42b The permanent is sacrificed at the same time the spell is announced (see rule 409.1a). The total cost of the spell is reduced by the sacrificed permanent’s mana cost (see rule 409.1f).

502.42c Generic mana in the sacrificed permanent’s mana cost reduces generic mana in the total cost to play the card with offering. Colored mana in the sacrificed permanent’s mana cost reduces mana of the same color in the total cost to play the card with offering. Colored mana in the sacrificed permanent’s mana cost that doesn’t match colored mana in the colored mana cost of the card with offering, or is in excess of the card’s colored mana cost, reduces that much generic mana in the total cost.

502.43. Ninjutsu

502.43a 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 creature you control to its owner’s hand: Put this card into play from your hand tapped and attacking.”

502.43b The card with ninjutsu remains revealed from the time the ability is announced until the ability leaves the stack.

502.43c A ninjutsu ability may be played only while a creature in play is unblocked (see rule 309.2f). The creature with ninjutsu is put into play unblocked. It will be attacking the same player as the creature that was returned to its owner’s hand.

502.44. Epic

502.44a Epic represents both a static ability and a delayed triggered ability. “Epic” means, “For the rest of the game, you can’t play spells,” and “At the beginning of each of your upkeeps, copy this spell except for its epic ability. If the spell has any targets, you may choose new targets for the copy.” See rule 503.10.

502.44b A player can’t play spells once a spell with epic he or she controls resolves, but effects (such as the epic ability itself) can still put copies of spells onto the stack.

502.45. Enchant

502.45a Enchant is a static ability, written “Enchant [permanent or player].” The enchant ability restricts what an Aura spell can target and what an Aura can enchant.

502.45b For more information on Auras, see rule 212.4, “Enchantments.”

502.45c 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 permanents or players that match all of its enchant abilities.

502.45d 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. Rules 212.4d-k apply to an Aura with the “enchant player” or “enchant opponent” ability in relation to players as they normally would for permanents.

502.46. Convoke

502.46a Convoke is a static ability that functions while the spell is on the stack. “Convoke” means “As an additional cost to play this spell, you may tap any number of untapped creatures you control. Each creature tapped this way reduces the cost to play this spell by {1} or by one mana of any of that creature’s colors.” Using the convoke ability follows the rules for paying additional costs in rules 409.1b and 409.1f-h.

Example: You play Guardian of Vitu-Ghazi, a spell with convoke that costs {6}{G}{W}. You announce that you’re going to tap a colorless creature, a red creature, and a green-and-white creature to help pay for it. The colorless creature and the red creature each reduce the spell’s cost by {1}. You choose whether the green-white creature reduces the spell’s cost by {1}, {G}, or {W}. Then the creatures become tapped as you pay Guardian of Vitu-Ghazi’s cost.

502.46b Convoke can’t reduce the cost to play a spell to less than 0.

502.46c Multiple instances of convoke on the same spell are redundant.

502.47. Dredge

502.47a Dredge is a static ability that functions only while the card with dredge is in a player’s graveyard. “Dredge N” means “As long as you have at least N cards in your library, if you would draw a card, you may instead put N cards from the top of your library into your graveyard and return this card from your graveyard to your hand.”

502.47b A player with fewer cards in his or her library than the number required by a dredge ability can’t put any of them into his or her graveyard this way.

502.48. Transmute

502.48a Transmute is an activated ability that functions only while the card with transmute is in a player’s hand. “Transmute [cost]” means “[Cost], Discard this card: Search your library for a card with the same converted mana cost as the discarded card, reveal that card, and put it into your hand. Then shuffle your library. Play this ability only any time you could play a sorcery.”
