驍勇印記

Text:

每當佩帶此武具的生物單獨攻擊時，你每操控一個其他生物，它便得+1/+1直到回合結束。佩帶（：裝備在目標由你操控的生物上。佩帶的時機視同巫術。）

Rulings:

• 6/22/2015 Count the number of creatures you control other than the equipped creature as Sigil of Valor’s ability resolves to determine the amount of the bonus. Once the ability resolves, the bonus won’t change, even if the number of creatures you control does.
• 6/22/2015 A creature attacks alone if it’s the only creature declared as an attacker during the declare attackers step (including creatures controlled by your teammates, if applicable). For example, Sigil of Valor’s ability won’t trigger if you attack with multiple creatures and all but one of them are removed from combat.
