Well, I'd rather not have to put gold producing holdings in the deck like we had to in the CCG.
Make the economy part of the controllable elements, via stronghold and/or plot/events deck...
It's always been too easy to suffer heavily from a bad gold start or getting only holdings on the turn where you need at least a body...
AEG improved it a lot in IvE+ introducing Legacy, Cycle, Kharmic and many refillable Holdings or really playable Event like Coronation Festival (with option for tutoring it). Have to say that, except overall dullness of first half of Ivory, these mechanisms helped a lot in term of game flow and reducing goldscrew/goldflow. So my opinion is - well designed cards/mechanism could easily utilize oldschool L5R gold system.

Cycle
Limited: If it is your first turn, choose one or more face-up cards in your Provinces. Put them on the bottom of your deck in any order. Then (after refilling Provinces), turn all cards in your Provinces face-up.
