Building a Commander deck in Magic: The Gathering starts with choosing a legendary creature as your commander. Include 99 cards, balancing lands, creatures, spells, and artifacts to match your strategy. Focus on synergy with your commander’s abilities. Ensure a variety of mana sources, removal spells, and game-winning cards. Remember, the deck must follow the color identity of your commander and use only one copy of each card.
