This card cannot be destroyed by battle. If this card is in defense position, destroy it. This card gains 500 ATK for each Fog Counter in the field. If this card destroys a monster with Fog Counter(s), you can Special Summon that monster at the end of the Battle Phase. If you do, destroy that monster at the End Phase.

Acho que o certo é "...on the field."
