4 rulings from Wizards of the Coast
- 1 October 2005If the enchanted creature was a token, it ceased to exist when it was exiled. Any Auras that were attached to it (including Flickerform) remain exiled.
- 1 October 2005The card that was enchanted comes back onto the battlefield first, regardless of whether it’s still a creature. Then any Auras exiled that can legally enchant that card come back. Any Auras that can’t enchant that permanent remain exiled.
- 1 July 2013If 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.
- 1 February 2014If the enchanted creature was enchanted by any Auras with bestow or any Licids, those cards will return to the battlefield unattached as creatures.
