Hmm I got inspired to do some playing with the scores for the full 12 years. Interesting to see the results over time. They are ranked in order of most years and then secondarily ranked by their average place in the top 10 over the years. Some decks had clear patterns over the time they appeared, so I've put comments next to them to indicate the trend. No comment means they've been reasonably stable, or for the bottom end of the list means they were trendy for some/few/one years and have since dropped off completely and don't appear anymore. Some decks near the middle of the pack I initially thought were disadvantaged as they weren't released at the start of the polling so couldn't rank evenly with older decks which have been around the full 12 years, but turns out most of these are getting less popular each year, with the exception of the Deviant Moon which currently seems most likely to become a new all-time-best to rival the classics and the Tarot of Dreams which is getting more popular each year both having appeared for the last 3 years)

Victoria Regina is the highest ranked deck that appeared only one year and then vanished. 1JJ has done suprising well to suddenly appear on the list after being on the market for so long, and to suddenly appear ranked so highly. It dramatically overtook crowd favorites like the Mythic, Hanson Roberts, Universal Waite, Morgan Greer, even the BBCats.
