Legendary Creature — Human Soldier
Vigilance
Other Soldiers you control have vigilance, trample, and haste.
: Until end of turn, Soldiers you control gain "Whenever this creature attacks, it deals 1 damage to defending player."

Rulings
Activating Commander Mustard's last ability multiple times will cause Soldiers you control to gain multiple instances of the triggered ability. For example, if you activate Commander Mustard's last ability twice and then attack with Commander Mustard, it will have two instances of the triggered ability. Both will trigger, and the defending player will take 2 damage.
