Vanishing 3 When Lost Auramancers dies, if it had no time counters on it, you may search your library for an enchantment card, put it onto the battlefield, then shuffle.

If an Aura is put onto the battlefield without being cast, the Aura's controller-to-be chooses what it will enchant as it enters the battlefield. An Aura put onto the battlefield this way doesn't target anything (so it could be attached to a permanent with shroud, for example), but the Aura's enchant ability restricts what it can be attached to. If the Aura can't legally be attached to anything, it remains in its current zone.
