You are thinking like a magician, not a layperson. I've performed plenty of effects where I have destroyed or permanently altered cards, and never once have I been asked to restore one. (Although Penguin offers plenty of TNR effects if that's what you want to do.)
If, after performing Tornado, somebody asked me to restore the cards. I'd just smile and say, "I'm a magician, not a faith healer!"
