Có thể kích hoạt hiệu ứng cuối cùng của Dragocytos Corrupted Nethersoul Dragon trong Standby Phase của tôi bằng cách chọn mục tiêu vào quái thú có 0 ATK không?

DARK 10

1 DARK Tuner + 1 non-Tuner Dragon-Type monster Cannot be destroyed by battle. When this card destroys an opponent's monster by battle and sends it to the Graveyard: You can activate this effect; this card can make a second attack on an opponent's monster in a row. During your Standby Phase: You can target 1 face-up monster your opponent controls; its ATK becomes half its current ATK, and if it does, inflict damage to your opponent equal to that lost ATK.
