You cannot Normal Summon or Flip Summon this card unless you have an Archfiend Monster Card on your side of the field. The controller of this card pays 800 Life Points during each of his/her Standby Phases (this is not optional). When this card is specifically designated as a target of the effect of a card controlled by your opponent, when resolving the effect, roll a six-sided die. If the result is 2 or 5, negate the effect and destroy the opponent's card. Also negate the effect of an Effect Monster that is destroyed by this monster in battle.
