You can only activate this card when an "Elemental Hero Clayman" on your side of the field is selected as an attack target. (If it is face-down, pick up and show the card to your opponent.) Destroy the attacking monster and the selected "Elemental Hero Clayman" to inflict 800 points of damage to your opponent's Life Points.
