Through the Breach

Rulings

Putting the card onto the battlefield is optional. When the ability resolves, you can choose not to. — 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. — If 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. — You choose all targets for the spell after revealing cards you want to splice, including any targets required by the text of any of those cards. You may choose a different target for each instance of the word “target” on the resulting spell. — You reveal all cards you intend to splice at the same time. Each individual card can be spliced only once onto any one spell.
