There is a lot of debate about this particular question. As someone who has been gifted decks and purchased her own, I don't believe any singular deck is better than the other. I think there are merits to having someone you love and trust gift you a deck (whether it was one you picked out or one they thought you'd like). However, if you are perhaps someone who isn't comfortable asking for this kind of gift and wants to purchase a deck yourself, there are things you can do to help bond yourself to your deck. Sleeping with it under your pillow, for example, or beside your bed. You can consecrate it using a simple consecration incantation. Or you can create a little cloth bag and carry your cards with you during your day. All these actions will help you become comfortable with your deck.
