I dont think you should play Key to the Archive only for its spellbook, but its not hard to find a deck that wants to make use of two extra mana of any combination of colors (and here it being any combination is important, because it allows you to cast off-color gold cards like Putrefy and Lightning Helix)

The rule went away in September 2014 because the two separate ban lists were confusing for new players, and the cards on this list were just banned from Commander in general as a result

But it also means that it may not always be the most potent choice in a given situation
