Start (or restart) the Hearthstone coach overlay — five native always-on-top panels (turn advice, HDT-style deck tracker, opponent tracker, coaching lessons, deck stats) fed by the hearthstone-tracker live feed. Use when the user asks to start/launch/restart the overlay, says panels are missing or stale, or wants the coach's advice shown in-game instead of only in chat.
