If the enchanted creature was also enchanted by Copy Enchantment, Copy Enchantment will return to the battlefield attached to that permanent. As Copy Enchantment returns to the battlefield, its controller may choose any enchantment on the battlefield for it to copy. It can’t copy Flickerform or any other Aura returning to the battlefield at the same time. If it copies a non-Aura enchantment, it returns to the battlefield unattached instead.
