A PCMag writer used an AI-assisted app called Replay Coach, built with GPT-5.6, to reach the top rank in *Magic: The Gathering Arena*. The app parses local log data from the game after matches to create a summary of what happened, which is then packaged into a coaching packet for an AI chatbot. The chatbot explains what went wrong, how to prevent mistakes, and what to watch for next time. For example, one analysis highlighted the mistake of letting "Lord Skitter resolve" when the player had a counter in hand, "Get Out," and identified a sub-optimal discard of "Winternight Stories" over "Sunderflock." Replay Coach also tracks removal cards, allowing the user to filter by turn or type, such as watching for "Avengers Disassembled" in red decks, "Day of Judgment" in white decks, and "Deadly Cover-Up" in black decks on turns three, four, and five. The writer, new to *Magic: The Gathering*, noted they lacked the knowledge to review games alone and found hiring a coach less effective for unfamiliar cards and situations.
