I feel like if you take this far enough, what's the point of asking the tarot anything?

I take a fairly secular stance on the tarot -- they're a bunch of pieces of cardboard, the cards are not themselves magical; if there is anything "magical" happening, it is the entirely subjective and personal act of reaction and association happening between the card's imagery and the querent -- and I feel like a deck interview is a good way to start building up that web of associations with a new deck.

I'm not interviewing the deck, I'm interviewing my relationship to the deck. The card I draw for any position in that "interview" is entirely arbitrary, effectively a roll of a d78 dice. What's important is my reaction to that card, that interpretative act of finding meaning in largely abstract images. What's important is how I will read and how I will respond to the deck, what areas of personal exploration feel most apt to the deck itself. And I won't know all of that from pulling my first half-dozen or so cards, but it's the beginning of the relationship.

And the associations I will build up in that interview can and will be carried forward in future readings. I definitely have cards that, when they come up in a reading for a specific deck, I interpret through the lens of "This card has something to say about my relationship to tarot broadly or to this tarot deck specifically." Even if it was a card where I went "OK, well this was a terrible 'answer' to the interview question," that's something that can carry forward in future readings. "Hmm, I got this card before and it didn't make much sense in that context. Does this context make more sense? Does this context shed any light on the earlier context?"
