Well, a natal chart can be interesting.
Three planets in an air sign, one in a water sign, one in a fire sign, and five in an earth sign. A water sign ascendent.
The most important pieces seem to be the element triplicities, aspects between houses and planets, and the ascendent.
What can be an interesting tarot exercise can be creating your natal chart with them, and where they fall within a tree of life or death.
A deck like Duquettes ceremonial Magick deck can be interesting, when you add the court cards on the outside, and patching in the minor arcana. The minor arcana can be interesting in itself. Each of them in that deck have Goetic seals at the bottom, which can tell you who you might want to invoke or evoke, in the top it tells you what decan or degrees within the sign it falls on, as well as a truncated pyramid that you can scry with.
It also includes names of angels from the shemhamphoresh, zodiac angels. From The Shem Grimoire you can get their seals and work with them.
The biggest key to me is understanding the negative and positive aspects they convey between aspects and signs. With that, you know what you need to work on within yourself. A personal and spiritual alchemy process, not to annihilate bad aspects but to tame both, not to always be too negative or too positive, but to control those aspects and qualities.
