if we're going with tarot cards, it should contain the 78 cards, the four suits and the 22 face cards. but you can name them whatever, as long as they get across the same meaning. like you could name 'the lovers' 'love' or 'justice' could be 'judgement'. my dragon deck changed pentagrams to coins, same meaning, but it's called something different.
when making the deck, i'd use white Bristol board, or card board with white paper glued onto each side. make sure they're all even of course, the back has to be all the exact same design. the faces, just draw what you feel best represents that card. making the cards, while a lot of work, sounds like a good idea, you can charge them with your energy, and get a stronger connection to each card as you work on them.
