The project targets Hearthstone Battlegrounds, an eight-player auto-battler with stochastic shops and battles, hidden information and nearly a thousand interacting cards, and frames the result as a test of whether LLM agents can carry a hard real-world problem from raw data to a competitive system.", "body_md": "Can LLM agents carry a hard real-world problem from raw data to a system that holds its own against people?
