Starlight Road has to be chained to the destruction effect, assumedly it's the Heavy Storm. Starlight Road will resolve first, but since Royal Decree is still active at the time, Starlight Road will be negated. Heavy Storm will then resolve and destroy all S/T cards. Because Starlight Road has to be chained to Heavy Storm in this case, there's no way to get Heavy Storm to destroy Royal Decree first and allow Starlight Road to resolve after, without adding additional cards, like a Mystical Space Typhoon at Chain Link 3. MST will resolve first, destroying Royal Decree. Starlight Road will resolve second, negating and destroying Heavy Storm. Heavy Storm has been negated and won't resolve.
