As your turn begins, untap your tapped cards so you can use them again. When a permanent is tapped, you can’t tap it again until it’s been untapped (turned back upright). You do this when you use a land to make mana, when you attack with a creature, or when you activate an ability that has the symbol as part of its cost ( means 'tap this permanent'). To tap a card is to turn it sideways to show that it has been used for the turn. This section describes the actions you'll take during a game, including tapping your cards, casting spells, and attacking/blocking with creatures in combat.
