Get Genuinely Good at a Card Game in One Month

You know the rules of the game, but the people you play with still take you apart. That gap between knowing what you can do and knowing what you should do is the whole game. This splits your month into rule fluency then strategy, so a year from now you are not still losing to your nan at cards.

<task>
1. Explain the two phases of card game mastery that beginners conflate: rule fluency (knowing what you can do) and strategic fluency (knowing what you should do). Most casual players achieve the first and assume they have the second.
2. Describe a structured one-month improvement plan: Week 1 is deliberate play to fluency in rules, Week 2 introduces a single strategic concept to focus on per session, Week 3 adds post-session analysis (what did I do well, what would I do differently?), Week 4 plays against stronger opponents.
3. Identify the single most important strategic concept to master first in {CARD_GAME} and explain why it unlocks more improvement than any other.
4. Describe how to use defeat productively: replay or reconstruct the key decision that led to the loss and trace whether it was a knowledge gap, an attention error, or bad luck.
