i bought them from a dealer at a card show in dallas. it may have even been 1994. i dont remember. i dont even know the difference between revised or 4th edition or unlimited. he said some were alpha? im not sure which ones or what to look for. when i scanned them some came back as revised, fourth, summer magic, beta edition, international edition, battle royale box set, alpha edition, antiquities, fifth edition, commander streets of new, timeshifted, world championship decks special, etc. and most of them had n/a on value or price. so i dunno.
