Perhaps (and this may be covered by the "other links" section) there can be a sort of cross-reference to different relevant sections of the official rulebooks. For instance, on followers there could be a line that says "See also: Aid" and for the example of
1R1, we could have "See also: Ring-bearer, Ring-bound, The One Ring (card type), Alternate Ring Bearers", etc.
In fact, it may be a good idea to have a wikified version of the different set guidebooks for such a feature as this. I for one would be willing to help translate the guidebooks, plural, into a wiki version.
