"An old friend"
If the question is "intense," I don't go to a light themed deck. I'll go to a deck that I've used a lot, and found that I've been able to draw positive guidance (versus positive outcomes) from the readings.
I had such a question recently, and I chose my Tarot of the Cat People deck. Because that is the deck I used solely for 18 years (it was a gift from my sister; my prior, Aquarian, deck had gone into "hiding"); and I'd found that, in the years I read with that deck, I always had something constructive and uplifting to say to people, no matter what the reading was about. I'm much more engaged with my MR decks, and some others at this point, and don't use the TotCP very often right now. But the particular question came up, and I wanted a bit of "safety" along with my truth! (Not that the others would necessarily have been alarming; it was just looking to talk to an old friend, at that point, with "whom" I'd had many, many conversations.)
