No Name misprints are indeed awesome. I used to collect one of each Yu-Gi-Oh rarity, and I also tried to find No Name misprints in as many different rarities as possible. Those aren’t added to that article yet, but here are the ones I have in my collection:
No Name misprints without imprint (obviously most preferred):
(those last two were added later, hence the loose picture)
No Name misprints with imprint (apart from the Horn of Heaven and German Goblin Elite Attack Force, the imprints are very feint and therefore definitely pack-pulled, but I would still prefer to one day get these rarities as actual No Name No Imprint misprints instead):
