امتياز وثائق العقد المظلم

If your opponent Special Summons a monster(s) with the same card type (Fusion, Synchro, Xyz, or Link) as a "D/D/D" monster you control (except during the Damage Step): You can inflict 1000 damage to your opponent, also, while this card is on the field, your opponent cannot Special Summon monsters with the same card type as that Special Summoned monster for the rest of this turn. If this card is sent to the GY: You can add 1 "D/D" monster from your GY, or 1 face-up "D/D" Pendulum Monster from your Extra Deck, to your hand. You can only use this effect of "Dark Contract with Patent License" once per turn.
