702.47 Splice
- 702.47a 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. Example: Since the card with splice remains in the player’s hand, it can later be cast 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. (refs: 601.2b)
- 702.47b 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.
- 702.47c 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. Example: Glacial Ray is a red card with splice onto Arcane that reads, “Glacial Ray deals 2 damage to any target.” 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. (refs: 612)
- 702.47d 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. (refs: 601.2c)
- 702.47e The spell loses any splice changes once it leaves the stack for any reason.
