6 rulings from Wizards of the Coast
- 14 June 2019If a spell is copied, choices made while casting it are copied, so the copy will have the same abilities spliced onto it as the original.
- 14 June 2019You reveal all cards you intend to splice at the same time. Each individual card can be spliced only once onto any one spell, although multiple cards with the same name may be spliced onto one spell.
- 14 June 2019If the spell is countered, any cards you spliced onto it remain in your hand.
- 14 June 2019The abilities spliced onto the spell happen last, after all of that spell’s other effects. Notably, the Golem won’t be on the battlefield yet if the spell has an effect that affects all creatures, all creatures you control, or similar.
- 14 June 2019If all of the spell’s targets are illegal when the spell tries to resolve, it won’t resolve and none of its effects will happen, including those from cards spliced onto it.
- 14 June 2019The legality of a spell’s targets is checked only as that spell begins to resolve. If the spell this card is spliced onto causes its targets to become illegal while it’s resolving (for example, by removing them from the battlefield) you’ll still create a Golem.
