Worked on the IIC2233/Syllabus repository to enhance game balancing by normalizing probability values for card abilities, ensuring that descriptions indicating certainty now consistently use a probability of 1.0 while preserving explicit percentages where specified. Addressed data management challenges by updating the cartas.csv file and aligning related documentation and assets, including a revised PDF and README entry, to reflect these corrections. Utilized CSV and Markdown to maintain clear, traceable records of changes, supporting both quality assurance and future maintainers. This work improved the reliability of card behavior in gameplay and streamlined the process for testing and onboarding within the project.
