what does vigilance do in magic the gathering
Vigilance is a keyword of an ability that existed as far back as Limited Edition Alpha with Serra Angel, but was retroactively keyworded beginning with the Kamigawa block. Creatures with vigilance do not tap when attacking (Prior to being keyworded, these creatures' rules text read "Attacking doesn't cause this creature to tap"), meaning they can still be used during the opponent's turn to block. Most creatures with vigilance are white.
