Eh, the problem with Royal Road is that it caused you to fish for certain cards, because some RR combinations were just way better than others. Combine that with the severe disparity between the usefulness of some cards over others and well. Very few cards ever got played, most were either thrown away or used for RR fodder.

At least in Shadowbringers, each card has a 100%, 66%, and 33% chance of being useful for each seal you get towards Divination, though that system isn't without its flaws too (I "love" going 6, 7, 8, 10+ draws without getting what I need).
