  Official Ruling
  Legolas, Master Archer's last ability triggers when you cast a spell that has multiple targets as long as at least one of those targets is a creature you don't control. It doesn't trigger multiple times if you cast a spell that targets a creature you don't control multiple times or that targets multiple creatures you don't control.
