Card type Monster
Attribute TRAP"TRAP" is not in the list (DARK, DIVINE, EARTH, FIRE, LIGHT, WATER, WIND, ?, ???, THUNDER, ...) of allowed values for the "Attribute" property.
Activate only when an effect that increases Life Points is activated. Negate that effect, and both players take damage equal to the amount of Life Points that would have been gained.
