# Love Live! OCG: Rule Verification
This is my understanding of the game logic, derived from reading `game_state.py` and `card.py`.

## 1. Win Condition
*   **Primary Goal**: Be the first player to successfully perform **3 Lives**.
*   **Tie-Breaker**: If both players reach 3 Lives in the same turn, the player with the higher **Total Score** (Sum of difficulty/score of completed Lives) wins? (Need to verify if score tie-breaker exists or if it's "Active Player Wins").

## 2. Core Stats (The Numbers)
*   **Hearts**: The "color" resource. A card might have `[2 Pink, 1 Blue]`.
*   **Blade Power (BP)**: The "attack" stat. Used for:
    *   Meeting "Total BP" requirements for some Lives?
    *   Triggering abilities (e.g., "If you have a member with 400+ BP").
    *   Comparing against opponents (e.g., "Retire opponent's member with BP < 300").
*   **Cost**: Energy required to play a Member.

## 3. The Turn Structure
1.  **Draw Phase**: Draw 1 card.
2.  **Energy Phase**: Gain 2 Energy (or more based on turn count?).
3.  **Main Phase**:
    *   Play Members to Stage (Max 3 slots).
    *   Play "Live" cards (The goal).
    *   Activate "Main" abilities.
4.  **Live Phase**:
    *   Select a Live card.
    *   **Check**: Do my Stage Members have enough Hearts (Color & Count) to meet the Live's requirement?
    *   **Bonus (Cheer)**: Flip top card of deck. Add its "Blade Icons" to the check.
    *   **Success**: If (Member Hearts + Cheer Icons) >= Requirement -> **Live Success!** (Score +1).

## 4. Observations on AI Logic
*   **Reward Signal Correctness**: My reward function gives `+1.0` for winning. It also gives `+0.1` per point of Score Difference. This encourages the AI to pick "High Score" Lives, not just the easiest ones, which is good for tie-breaking.
*   **Critical Blind Spot**: "Effect Precedence." If a card says "You win instantly if you have 5 Honoka cards," my current engine might miss that if the `check_win_condition` function doesn't explicitly look for that specific flag.

**Is this accurate to your physical game?** Specifically, does the "Cheer/Blade Icon" mechanic add to **Hearts** or **BP** for the Live check?
