    Description, as the server wrote it
    Use this when the user asks what a set is worth, what it costs to complete, or which cards in one set are the most valuable. Returns the cost to complete the set in singles today (one copy of each collector number at its cheapest printing, USD, the same figure as the set page), the master set total (every printing we price, labeled separately), the 25 most valuable singles and the 10 priciest sealed products of the set, plus companion sets that ship in the same packs but are catalogued separately (for example a Classic Collection or Trainer Gallery subset) with their own totals. Needs a group_id from search_cards.
