Forum:Effect of Stygian Sergeants

I was just wondering about the card Stygian Sergeants. As it doesn't say 'once per turn' or anything similar in it's card effects, say I destroy a monster with it, activate its effect, and destroy another monster with it's second attack. Would I be permitted to use its effect a second time, increasing its ATK by another 800 and attacking yet again? If anybody can please help me with this, I thank them respectfully.
