The Celestial Draft Pack was released in June 2009, more or less at the same time as the Celestial Edition basic set. Except for the 3 draft-excluisive cards (Brilliant Artisan, Riverside Port, and The Shrine of the Sun Lady), which are identified with «Celestial Draft» as their set indicator, the rest of the cards are identical to their Celestial Edition counterpart, so there is no reliable way to tell them apart, unless you have the chance to open the pack yourself.
