Bring your builders set (enough cards to build a solid deck) and get ready to cook up a creative new deck, featuring the âsecret ingredientâ card that will be announced when the tournament begins! Players receive three (3) copies of the ingredient to include in their decks, which will be judged on three points: creative use of ingredient, style, and of course, performance in competition.
