Great question — and thank you for taking the time to dig into the details!
You're absolutely right that there’s a small mismatch between the chart and the text. To clarify: only Face Cards (Jack, Queen, King) and Aces trigger Threshold Moments.
The 10s sit just below that — they're important, high-stakes cards, but they don’t activate Threshold Moments. I’ll make sure the next PDF update clears that up more explicitly. Really appreciate you pointing it out!
