During January 2025, Dextar M focused on stabilizing card interaction logic in the magefree/mage repository, specifically addressing a critical bug involving Bello, Bard of the Brambles and its dependencies with other cards such as Ashaya, Soul of the Wild. Using Java and leveraging skills in card game logic and unit testing, Dextar corrected the dependency handling mechanism, ensuring accurate interactions across various card types including artifacts and enchantments. Comprehensive regression tests were added to cover overlapping effects, which improved test coverage and reduced the risk of future regressions. This work enhanced the reliability and maintainability of the game’s codebase.
