Forum:Will Negate and destroy work in cards that can't be destroyed by card effects?

Say I summon Red Nova Dragon, next turn, someone tries to attack it and I try to use it's second effect, say a card like crystal wing uses its effect to try to negate and destroy red nova.

Now since red nova cant be destroyed by cards effects and effects have to resolve, would crystal wings effect only negate nova but not destroy it or would it not work at all?
