Forum:Creature Swap vs. Blast Sphere

When a monster attacks a face down Blast Sphere, on my next Standby Phase It's destroyed I get that. What I want to know is if I were to use creature swap on the monster and switch it with my opponent, would I still lose the life points, since it was mine originally, my opponent loses life points, since now it's his, or is the effect negated?
