Here are Cardcast's guidelines for writing cards: Keep in mind that I do have the right to change the way a submission is worded so it sounds better as a card. Make sure you add WHITE: or BLACK: in front of whichever one it is. Come up with ideas for call cards (black cards, which have blanks that you fill in) and response cards (white cards, which fill in the blanks the black cards give), and I'll add them to the deck. I want help in trying to create an Ace Attorney-inspired deck for use in Pretend You're Xyzzy. There is currently no way to see which, if any, Cardcast decks a game is using from the game list. The Cardcast decks currently in use for a game is displayed in the game's chat when a player joins the game. To see which Cardcast decks are in use for a game, anyone may type /listcardcast. A notice is broadcast to every player in the game. To remove a Cardcast deck from a game, the game host must type /removecardcast 5CODE. To add a Cardcast deck to a game, the game host must type /addcardcast 5CODE, where 5CODE is the 5 character code for the deck. The client UI needs a fairly significant overhaul to properly support these externally loaded decks. Right now, the only way to add or remove Cardcast decks is via chat commands. Temporary hacky way of adding decks to the game. 5CODE is the 'Play Code' on the deck's page, or at the bottom right of its overview card.
