Hi! I'm the creator of YGOWB. I wanted the custom Yu-Gi-Oh cards people imagine to become cards they can actually play. Card Studio breaks effects into trigger, requirements, cost, targets and outcome. The engine executes the supported blocks, so a card can go straight into a deck for testing. Arbitrary written effects still need to fit those blocks. Create a World for your group, choose its card pool and banlist, and decide whether new cards need review. Then practice against the computer or duel online, using classic 2005-era rules. YGOWB is free and runs in your browser at https://ygowb.com. An account is required. I'd love to hear which card idea you'd try first, or where the editor makes an effect difficult to express. This is an unofficial fan project, not affiliated with Konami. Some card artwork is AI-generated; art and effect assistance are optional.
