Filter EDHRec results to only show Pioneer legal cards
Filters EDHRec results for cards that are pioneer legal. I did this to playtest a pioneer-only version of Commander with my playgroup. The script works by intercepting the card results from the server and checking each card's legality via the scryfall API. It's a little buggy, but I will clean it up and add more filtering options (e.g., drop down of different sets) if there is any demand. Or if I get bored.
