6/1/2005
If one of the targeted lands isn't a legal target as Shifting Borders resolves (say, because it has left the battlefield or become untargetable), the exchange doesn't occur.
6/7/2013
You reveal all cards you intend to splice at the same time. Each individual card can be spliced only once onto any one spell.
6/7/2013
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.
6/7/2013
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.
6/7/2013
If all of the spell's targets are illegal when the spell tries to resolve, it will be countered and none of its effects will happen.
