Darkbishop Archfiend
The controller of this card pays 500 Life Points during each of his/her Standby Phases (this is not optional). When an Archfiend Monster Card on your side of the field is targeted by the effect of a card controlled by your opponent, when resolving the effect, roll a six-sided die. If the result is 1, 3, or 6, negate the effect and destroy the opponent's card.
