Lost Auramancers

Vanishing 3 (This creature enters the battlefield
with three time counters on it. At the beginning of
your upkeep, remove a time counter from it. When
the last is removed, sacrifice it.)
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 your library.
