I'm not into all this stuff. However, out of curiousity, I took a quick peak in the big Regardie book on the Order of the Golden Dawn. Apparently, the OGD used tattwas, in the form of tattwa cards, for scrying. On the other hand, tarot cards were used by the OGD for creative visualizations in ceremonies. As well, tarot cards and other forms of divination were used for developing intuition.
In the OGD manuscript on scrying and astral projection, it is indicated that the seven planetary Tarot trumps were employed as 'important test symbols' but that manuscript doesn't indicate how exactly those trumps were to be used. However, in any event, Saturn was for memory, Jupiter for construction, Mars for anger, impatience, Sun for vanity, Venus for pleasure, Mercury for imagination, and the Moon for wandering thoughts.
And a quick ride on google.com located this link to a contemporary article on tarot scrying:
