Hi there! Let me see if I can help you:
- You only need the PDF and a regular deck of cards to play. So yes, you can play it perfectly just using your tablet and any standard deck of cards you already own. The physical booklet and the custom deck of cards are optional. No need for a printer.
- If you purchase the PDF, you'll be offered links to purchase the physical booklet and the custom deck of cards at-cost (meaning you only pay the cost of production + shipping). But again, you don't need them to play, it is just a convenient option in case you're interested.
I hope that helps!
