These are special moves for Racetrack and rules for using the gravel bed. I would recommend to use the special moves on a limited bases, just negotiate which move can be performed how often. I am currently thinking of a card-deck distribution so that i can order an Artscow deck someday... You would get a couple of cards and if you want you could use a special move by discarding that card. Not sure at the moment if/how you would get more cards in the game... have fun with these!
