Magic: The Gathering Chaos Extractor
This program will take the Scryfall json (https://scryfall.com/docs/api/bulk-data) and the XMage sets directory (https://github.com/magefree/mage/tree/master/Mage.Sets/src/mage/sets but you'll want whatever version your server is running) to create most of a Draftmancer file.
Place the XMage directory and the both the Scryfall Oracle Cards and Default Cards downloads inside the /src folder. Remove the date from the names of the Scryfall .json files. Then cargo run from the base directory of the project.
This will create three files. Once you've done one run, you can disable the mage_compatible() call from main() since that function's output will be stored in the EVERYTHING_mage.txt file. Re-run it and re-copy the set folder when you update XMage to have the latest cards.
