A guy on reddit named Jambarama told me about this single elimination tournament they did, only using the old gold bordered World Championship collectible decks. Here are the results!
Winner: 2002 Psychatog
2nd place: 2008 Faeries
Academy and Memory Jar both retired / not invited.
Double elimination except for the final: this time we did a loser’s bracket, but the winner of the loser’s bracket took 2nd place without challenging the undefeated winner of the winner’s bracket. So Swans had a good run but lost to Delver and Shrine Red.
Winner: 2012 UW Delver
2nd place: 2011 Shrine Red
Double Elimination. Academy retired.
Since the Tolarian Academy deck had won Chingsung’s tournament and the Pax Prime tournament, I decided to retire it “to the hall of fame” and see if Memory Jar could win a 2nd time without Academy in the way. I put up a sign that read “What’s the 2nd best standard deck of all time?!!!” and players who bombed out of the main event would come over and play a match or two.
Winner: 1999 Memory Jar
Runner-Up: 2010 CawBlade
This tournament only included my gold-bordered World Championship decks, the 1996 Pro Tour commemorative decks, and “Deckmasters: Garfield vs Finkel” decks. I do recall that in the semis, Psychatog resolved Upheaval only to have Ghazi-Glare drop a land and play Pithing Needle naming Psychatog.
