Vigilance



Vigilance is a static ability that means the affected creature does not need to tap when attacking.

Example
Amelia attacks with her Griffin Sentinel. This would normally cause the Sentinel to be become tapped, but because it has vigilance, this means that it remains untapped and thus can block any thing that could attack her next turn.
