Instant, UR (2) Change the target of target spell with a single target. "We can't beat the necromancers in numbers or raw power. We must beat them with ingenuity and timing." —Rannon, Vithian holdout

10/1/2008: Swerve targets only the spell whose target will be changed. It doesn't directly affect the original target of that spell or the new target of that spell.
10/1/2008: You don't choose the new target for the spell until Swerve resolves. You must change the target if possible. However, you can't change the target to an illegal target. If there are no legal targets, the target isn't changed. It doesn't matter if the original target of that spell has somehow become illegal.
10/1/2008: If you cast Swerve on a spell that targets a spell on the stack (like Cancel does, for example), you can't change that spell's target to itself. You can, however, change that spell's target to Swerve. If you do, that spell will be countered when it tries to resolve because Swerve will have left the stack by then.
10/1/2008: If a spell targets multiple things, you can't target it with Swerve, even if all but one of those targets has become illegal.
10/1/2008: If a spell targets the same player or object multiple times, you can't target it with Swerve.
