My inside sources have leaked to me that "tapping" your cards will be changed to "flapping" your cards, and that each card will be a solid slab of quartz crystal whose stats and effects are determined by physical properties like resonant frequency, color, and impurities.
seriously tho, would be kinda rad if they did. like, there's a stupid amount of existing cards already & proxying is getting more & more common. make a Totally Not Just the Same Thing Again to milk to death. meanwhile, the players with a certain degree of passion for the game could keep enjoying it in peace.
