✨ Core Features

• **🚀 Native C# injection, extremely smooth**: Completely abandon the cumbersome OCR screenshot recognition solution. This Mod directly reads the card instance object at the bottom of the game, the performance overhead is absolutely 0%, and the matching accuracy is as high as 100%.
• **🛡️ Intelligent scene recognition**:
• **Stealth during battle**: During a fierce battle, whether it is a hand card, a draw pile or a discard pile, the winning rate panel will automatically hide and will never interfere with your battle vision.
• **Store Adaptive Layout**: When you visit a merchant, the panel will smartly jump right above the card, perfectly avoiding the gold coin price tag at the bottom; and when you click on the "Card Removal Service", it will obediently return to the bottom of the card, and will never pierce the black background mask.
• **🎨Dynamic Rating Frame**: The panel has an extremely beautiful outer frame, and the color of the frame will change according to the card's comprehensive rating (gold S level, silver A level, copper B level, etc.), allowing you to pick out the "must-get cards" at a glance.
• **🧹 Clean Mode**: Built-in logic automatically filters basic transition cards such as "Strike" and "Defense" to keep the interface clean.

**Rating Criteria**:

• **💖 S (Must Get)**: Rating > 48 (shows dazzling golden border)

• **🦾 B (Available)**: Rating > 35 (renders with a solid copper border)
• **🥶 C (Mediocre)**: Rating > 28 (gray border)
