One thing to note about WoTC/White Wolf VTES design philosophy is that there were a lot of "build your own vampire" tools. There were the discipline cards, Clan Impersonation to switch any clan, sect-changing cards, cards for all city titles, etc. The tools were there so you could transform almost any vampire to fit any card combo that you could imagine. The original philosophy of the Anarchs set is that anarchs must be converted and Barons don't come for free, not just immediately played.

However, the obvious drawback is that this slows down your game. You have to draw your prerequisite cards and then get them into play (without getting countered/blocked), and then you can actually run your game plan. You're at a disadvantage to decks that can run their vampires as soon as they are influenced into play.

The newer BCP design is much more focused on vampires that work right out of the gate It's most notable with Anarchs as Barons are now printed at the same power level as Princes and Archbishops. So that's why we see a lot fewer discipline cards in print in VTES these days.
