Forum:Stardust Dragon/Vanity's fiend

So I have a "Vanity's Fiend" and one of my friends has a "Stardust Dragon". So let's say I have "Vanity's Fiend" out and I use "Mystic Plasma Zone", so they use the "Stardust Dragon" to negate it. If "Vanity's Fiend" was destroyed in a different turn, could the opponent Special Summon the "Stardust Dragon" in a different End Phase? Or does it have to be the turn it's effect is used?
