Halloween was always my favorite holiday/occasion and autumn is far and away my favorite and most-relished season.
For those reasons, no decks currently out there meet with my approval as either Halloween-y or autumn-y enough. Gothic and vampire-y do not capture the spirit of the season for me, perhaps because they don't include enough of the seasonal/natural environment. I also don't like being locked into one theme for a deck that I would rather be Halloweeny generally and not focused on vampires alone or this or that scary narrative alone.
The Halloween Tarot, which was among the first decks in my collection and which I used to read at many events, does have the required seasonal flavor but it's too cutesy and humorous to for me to like using it as an all-purpose deck. Also, it too doesn't have the natural autumnal environment I want.
I really just want a serious-toned autumn-themed (northern hemisphere) deck and nothing else will satisfy me. For the time being, I'm willing to settle for a very starkly delineated autumn in one of the suits, but all the decks that have very clearcut autumn suits are unsatisfactory to me for other reasons (like the Hertz Faerie Tarot, which is hampered by, well, faeries).
As to the question of the thread, oh, the usual suspects: Archeon for the so-called "darker" deck [what is dark about this deck other than its literal, murky coloring?], Hudes for a slight autumnal feel, probably the Fallen Angel Oracle as mentioned above although I don't care for oracles and have to push myself to use the few I have, and, if I can stomach handling the sticky brick-like thing, Robert Place's Vampire Tarot.
I'll have to reconsider Sacred Rose in light of the recommendation, although my copy's out of reach at the moment.
. I have quite a few deck for the season:
