Make a Deck-Building Card Game Approachable for a Complete Newcomer

The rulebook assumes you already understand why you are buying cards from a shared market and shuffling them into your deck. If you have never played a deck-builder before, that assumption leaves you confused by turn two. This translates the core concepts into plain terms and gives you a simple starting strategy so the first game actually makes sense.

**Translate** the core concepts of deck-building into plain, practical terms:

2. The core vocabulary: explain hand size, buy phase, action phase, and shuffle triggers in plain language
3. The key strategic concepts a newcomer needs on turn one: thinning the deck, tempo, and when to buy points versus engine pieces
4. The most common newcomer mistakes and a one-sentence remedy for each
5. A simple starting strategy for {GAME_NAME} specifically that avoids the most common pitfalls
