/**
* 702.45. Splice
*
* 702.45a Splice is a static ability that functions while a card is in your hand.
* "Splice onto [subtype] [cost]" means "You may reveal this card from your hand
* as you cast a [subtype] spell. If you do, copy this card's text box onto that
* spell and 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
* 601.2e-g.
*
* 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.
*
* 702.45b 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.
*
* 702.45c 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, card 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.
*
* 702.45d Choose targets for the added text normally (see rule 601.2c). Note that a
* spell with one or more targets will be countered if all of its targets are illegal
* on resolution.
*
* 702.45e The spell loses any splice changes once it leaves the stack (for example,
* when it's countered, it's exiled, or it resolves).
*
* Rulings
*
* You must reveal all of the cards you intend to splice at the same time. Each individual card can only be spliced once onto a spell.
* If you have more than one card with the same name in your hand, you may splice both of them onto the spell.
* A card with a splice ability can't be spliced onto itself because the spell is on the stack (and not in your hand) when you reveal the cards you want to splice onto it.
* The target for a card that's spliced onto a spell may be the same as the target chosen for the original spell or for another spliced-on card. (A recent change to the targeting rules allows this, but most other cards are unaffected by the change.)
* If you splice a targeted card onto an untargeted spell, the entire spell will be countered if the target isn't legal when the spell resolves.
* If you splice an untargeted card onto a targeted spell, the entire spell will be countered if the target isn't legal when the spell resolves.
* A spell is countered on resolution only if *all* of its targets are illegal (or the spell is countered by an effect).
