Yeah, Quick Summon isn't a good example since it changes the attack target, while Magical Goodbye/Rulings states that if an attack doesn't have a target, the attack is nullified. Even if the target used to be in the center.

In other words, you can't change targets just because your target disappears. You can only change targets with a card effect.
