So recently I got this question on my Tumblr
And here’s the advice I can give
Tarot cards and decks are mainly used to give advice on situations going on in life and ways to help your future; and every deck has a different personality and energy to them making no deck the same.
Also if you don’t have a deck already a great deck to start out with is the classic Rider Waite deck and most beginner books tend to reference that certain deck. If you don’t have money for a physical deck I’d download the Golden Thread tarot deck since it’s free, it’s really pretty, and the app comes with tarot advice as well. The app labyrinthos helps too since it also teaches the basics of tarot.
And lastly, a good site to reference is Biddy Tarot. They’re honestly a great resource and I still check them from time to time when I get rusty.
