Forum:Six Samurai's second effect not negated successfully

Some Six Samurais has effects that states "If this card would be destroyed, you can destroy another "Six Samurai" monster you control instead."

If you have three Six Samurais face up on the field, ex. Kamon, Yaichi, and Zanji, and your opponent has a Stardust Dragon, you activate Yaichi's effect on their set magic/trap, and the opponent use Stardust to negate it.

Now, if I choose to use Yaichi's second effect to prevent it from being destroyed, would the set magic/trap still get destroyed? And also, since Stardust Dragon didn't successfully destroy the target, will it still come back at the end of the turn?
