Yeah, your two decks kinda stood out in the database report I built - overall 26 duplicates. And according to historical snapshots, you built the deck somewhere around march 2008.
The issue itself existed since 29.oct.2007. It seems only 3 people noticed it until now, and only one decided to report it. The other guy was 'amaster', a once active player and forum contributor, but he hasn't logged in for 4 months now. I don't think he mentioned it either. And finally there's JimmyMethod who's the author of this thread.
