What is vigilance in magic the gathering?

In Magic: The Gathering, vigilance is a keyword ability that allows a creature to attack without tapping. Normally, when a creature attacks, it must tap (turn sideways) to show that it is attacking. However, a creature with vigilance can attack without tapping, allowing it to both attack and block on the same turn.

Creatures with vigilance are valuable in combat situations because they can attack aggressively while still being able to defend against enemy creatures. This ability is particularly useful in aggressive decks that want to put pressure on opponents while maintaining a strong defensive position.

Vigilance is indicated by a symbol of an eye on a shield. Cards with vigilance will have the ability explicitly written out on the card. Overall, vigilance is a powerful ability that can give a creature versatility and flexibility in combat situations.
