Once you load the page you have everything you need to build some custom cards. This project was produced mostly as a tool to help its author more easily prototype custom cards to try in Table Top Simulator with and around Cryptozoic's own titles, as well as an excuse to brush up on some technical skills. Instead please buy Cryptozoic's own deck building games utilizing their engine such as the DC Deck Building game, they are excellent. No cards produced using this tool should be used to profit from. It is open source and available on GitHub. This application is a fan creation by Jacob Fischer with the sole intent of making it easier to try custom cards in Cryptozoic's Game Engine.
