Well, my favorite of the moment is the Tarot of Vampyres, I love it and I've been using it non stop and exclusively for a year now. I've also done a Primary Deck Reflections on it as well as a Intensive Deck Study. But I think asking for the "lifetime" deck when I still have 30-40 years ahead of me it's hard to swear I'll love the deck that long. I'm sure of one thing though, I've bought three copies so far and plan to buy a fourth one (my first copy got ruined unfortunately) so I definitively plan to ensure to have copies of the deck if I'm still in love with it 30-40 years from now.
