Tell me about your subcollections!

I don't have any subcollections yet... keyword yet. Though a lot of my tarot decks have a historical influence (what do you expect from a History major haha). I would love to expand my historical tarot collection (both influenced by history and historical reproductions) to be a subcollection but I'm just so darn picky. Of course I absolutely fell in love with The Tarot of Delphi deck only to find it's out of print at the moment. :'(

I seem to have some esoteric, metallic, dark/gothic, and vampire deck sub-collections. I plan to start a reveals-my-hidden-neuroses/psychoses sub-collection soon.
