Contains 2 metal tokens (one or both are premium); 11 limited edition, out of print, and/or special tokens; and one artist proof (low value up to a foil Inquisition of Kozilek).  5 of the artist proofs have sketches on the back with the highest level custom art on the back.  This is slightly better that the first edition, in that the odds of getting original art is 1/8 vs 1/10.  Also, I don't know what is in each pack.  Shuffled after sealing and before numbering.
