Ohhhh this is a great discussion! 
Excited to dig into this one~ 
I dabble with a few different forms of divination, with Tasseography (tea leaf readings 
) and Tarot 
being my current favorites. Despite my adoration for tarot decks, it’s actually been a while since I got a new one!
Like @MeganB, I believe that my decks (or at least the ones I used for readings) are an entity all their own- and oh boy do they have personalities! 
My current go-to deck is the Anima Mundi and it lets me know when it’s time for a cleansing.
When it comes to cleansing I like using moonlight 
, crystals 
, and a spoken blessing 
to cleanse the deck.
When it’s not in use for readings or for spellwork, my deck has a special drawer for a home. I never take it out of the house- mostly due to current lockdowns but also becomes I’m terrified I would lose cards somehow along the way 
I love my cards not just for magickal readings, but also a source of inspiration for creative works! I love using and seeing how the cards can inspire art or other creative processes 
Looking forward to learning more about how everyone handles and practices with their unique divination tools! Thanks for the fun exercise, @MeganB!
