Rulings (6)
An Aura spell on the stack targets the object or player which it will enchant upon entering. Thus, an Aura spell is a "spell with a single target", which means you may use Swerve to change that target. Doing so will cause it to enter enchanting the new target rather than the original one.
If a spell targets multiple things, you can't target it with Swerve, even if all but one of those targets has become illegal.
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.
