A quick search of the internet for oracle cards reveals a dizzying number of choices. How do you find the perfect deck for you? For myself it has always been "do the cards resonate with me?" Most of the time when I am choosing a deck it is the beauty of the illustrations on the cards that first draws me in but it is the beauty of the messages that those cards convey that ultimately convinces me to purchase them. Intuition also plays a role...if I'm not feeling it, I'm not buying it.
Pull a card, read the message in the guidebook. If it speaks to you immediately then your relationship with the deck was meant to be.
