Prerelease cards are selected expansion reprints with a Prerelease or expansion-logo stamp; staff versions were produced for event organizers beginning with the Diamond & Pearl expansion.
Why collectors care
Prerelease and Staff stamps identify event-distribution copies, and Staff copies are often more limited because they were distributed to organizers rather than regular participants.
Look for a PRERELEASE, expansion-logo, or STAFF stamp on the card face.
Prerelease and Staff stamps are parent identity modifiers because the stamp changes the distribution identity of the physical card.
