Those are the ones! I can't speak for the other three decks, but the Factions & Locations option have been very helpful, for me.
More experienced Blades GMs may find them less useful, as they primarily rely on information already present in the core book.
Nonetheless, I found having relevant, thoughtfully grouped, and condensed information available on cards, to be a lot more convenient than loads of extra A4 sheets at the table.
