banlist.json

Banlist.json contains a your campaign's banlist.
Each card name is in an Array of a Key-Value Pair, the key for which is the "Banlist Status":

• "0" - Zero copies of the card may be included in the Deck.
• "1" - Up to one copy of the card may be included in the Deck.
• "2" - Up to two copies of the card may be included in the Deck.

If not on the banlist, you may include up to 3 copies of the card in the Deck.

you can "update" the banlist during a bans event. This only updates the list for the one user encountering the event.
