How to use them
As to how I use them within the week, that varies a great deal and is down to my schedule/time management, whims, and what I feel a particular deck is good for.
For instance, when I've used erotic-themed decks, I've liked to use them to read for others to see how they apply to different situations, but as it's not really "the thing" for face-to-face querents (at least mine, who are usually either strangers or distant acquaintances referred to me), I read for people here on the forum, in the Deck of the Week reading threads, or the erotic threads or what have you.
Other decks, I don't feel the need to read at all. I can study something to do with their symbology or history. Or, as I have done this week with the Transformational Tarot, I can do exercises or imaginative games with them (I'm using games from The Tarot Playbook).
Still other decks are the sort of deck I reserve for self-readings, especially ones meant to mine the subconscious. I might do one reading with that deck and spend all week interpreting it.
Lots of different stuff for you to try.
