Hey there! The maximum confrontation under the most extreme circumstances would indeed be 5 cards for the player vs. 7 cards for the Seer. We looked a bit into probability tables but have no clear table yet. It's rather different from more straightforward dice systems due to the interaction between trump suits and the number of cards held in hand.

Thanks for the comment! I really love what you’ve done with this skill test system—it’s brilliant. I’ve actually been using it in my solo UVG campaign, though I’ve adapted it slightly based on your ideas.
I like to use the meaning of the winning card or hand to set the tone of the outcome—especially when I’m using an illustrated deck like the Rider-Waite.
Optionally, I draw a card from the court or major arcana decks to flavor the result.
Alternatively, I include 5–10 court or major arcana cards in the skill test deck as wild cards. These can trigger unexpected events during tests—either positive or negative—depending on the hand. The impact is usually stronger if it’s a major arcana card.
Thanks again for the inspiration—your system has really added a lot to my sessions!
