Could you build this?
Partial The benchmark UI, RL wrapper, and data pipelines are codeable with AI help. A faithful, full-content Hearthstone Battlegrounds engine that matches the real game's rules and card interactions is a large, detail-heavy effort that also needs careful evaluation design.
What it would actually take: The stack is a game engine in Python or TypeScript exposing a Gym-style RL interface, with card and minion data extracted from the game's card database. The hard part is reproducing the game's exact combat, trigger ordering, and hundreds of card-specific edge cases so that results are faithful. Building it requires deep knowledge of the game's mechanics, rigorous test suites against real game logs, and RL/benchmark design expertise.
