As far as I can tell (And i am a little nobody) tarot cards are basically an alphabet to interact with weird stuff that is beyond our normal comprehension. Most likely, it is only a set of archetypes that we use to invoke energies and knowledge that we don't know how to operate with, under the regular scientific model.
So no matter what alphabet you use, as long as it makes sense to you and to the person you are talking to. This is why lots of people can use different cards, because the power is within yourself, the cards are only a way to organize your ideas.
If I'm correct then, the deck is irrelevant as long as the energies it represents are resonating inside of you. You could create your own alphabet with the hanafuda cards, maybe it won't be as powerful as a tarot deck which already has meanings inserted, but if it resonates strongly with you then I would say give it a try.
I would recommend tarot first, just to get familiar with using alphabets made of images
