If you can find a deck that has been printed from woodblocks, you will be in possession of a magical kind of deck.
My only such kind is the Tarot Flammand, from Carta Mundi. This is a Belgian type of the late 18th century, and is illustrated in Kaplan. It is the one with Bacchus and the Spanish Captain instead of Pope and Popess. It is beautiful and is my favorite of all. I feel like I am actually touching the figures, and the cards feel somewhat fragile and temporary, like a deck meant to be used and discarded, as it no doubt was. So it is a treasure.
For pure Tarot de Marseille, I like the Piatnik best. It is large and authentic feeling, also late 18th century, although no date is given. The Heron Conver is considered the most careful facsimile of the 1761 deck, I understand. I have the cards, and I love them, but I have not warmed up to them like these other decks. I believe the lamination is too thick, and I wonder if they are smaller than the originals.
The one deck I would love the most is the Camoin bicentennial, printed from the original woodblocks of the 1760 deck. I haven't been able to get it yet.
My advice is to get any Tarot de Marseille, except for the Tarot Classic of US Games. This one has no life, in my opinion, and may turn you off Tarot de Marseille. I haven't looked at it for years, so maybe my opinion will change if I look at it again, with fresh eyes. I'm sure it must have something to teach.
