This is a Relinquished deck for the short-lived May 2003 format. With the introduction of Sinister Serpent in this format, Relinquished became much more powerful! The main deck was originally created by Saberwolf94. Please check out his deck profile video at this link!: youtube.com/watch?v=AKDpWh6EXAU
Happy Halloween! Relinquished is a Dark Fiend monster, very spooky!
