There are concerns with using the cards, I'm sure.
Likewise, automating the dice outcomes.
Some can't do those.
It's not like the cards are a huge problem; the card format isn't essential. And the full text is in the book.
Automating the 2d12 Disparity Dice is more of an issue. ALmost all can handle 2d12... but some of the free ones don't let you have different colors per player, and don't have the ability to do comparisons of the two dice. One I tried years ago didn't show you the dice, let alone in order rolled, instead just the total of the roll.
I like the DD, so I'm planning on implementing it into my Discord die-roller... but I'm nearly at the limit of my ability to refactor my own code.
