Currently set data and card set numbers are taken exclusively from YGOPrices, but they have a few shortcomings.
First, they don't support OCG cards, second the set numbers require normalization, because of how they scrape the data themselves.
I feel we should find a way to grab card set numbers and sets from the Wiki as well, and consider YGO Prices only as a source price. This will help with the OCG cards and Alternative Price Sources issues.
