In my opinion, tarot cards are literally just cards with pretty(or creepy in some cases) pictures. As long as you can make a connection and capable to understand what you are seeing it'll be fine. My first deck of cards were printed images of a set and taped onto card boxes and I still made a connection. Go for it, :).
1. those are both smart ideas!
2. where did you find it? like the site.
3.how do you do it with regular cards? :D that sounds awesome!
4. no it wont weaken the cards! :D
I don't think so, but you should probably print it on thicker paper to make them more card like. I know people who make their own cards, if you feel drawn to the cards, and you cleanse/charge them, it should work the same.

I really like the pictures on this deck and even though I havent been using it long, I feel like I have already established a strong connection with my deck! I printed them on a thick stock note card paper. They're really big but I'm really happy with them!
