What the sources say

• Generated while playing

  For the 2014 release of Hearthstone, the in‑game AI opponents used static, designer‑tuned decks and rule-based behavior for single‑player (i.e., the AI during play was not a generative content system). [1][3]

• Development workflow

  Blizzard later experimented with machine‑learning tools in internal hackathons (a 'Free Your Mind' project simulated tournaments with computer‑piloted decks), but this was a development/tooling experiment and not documented as part of Hearthstone’s 2014 release pipeline or live generative content systems.
