For effects that read "you can only ACTIVATE this card/effect once per turn/Duel" if the activation of the card or effect is negated, you can activate the card/effect again in the same turn/Duel. So if the activation of "The Seal of Orichalcos" is negated by a card's effect you can activate another "The Seal of Orichalcos" in that Duel. For effects that read "you can only USE this card/effect once per turn/Duel" if the activation of the card or effect is negated, you cannot activate the card/effect again in the same turn/Duel.^[1]

Even if during the Duel the opponent activates "The Seal of Orichalcos", you can activate "The Seal of Orichalcos".^[2]

If "Forbidden Dress" or "Forbidden Lance" are activated in a chain to "The Seal of Orichalcos" targeting a monster that was Special Summoned, the Special Summoned monster is not destroyed once the effects of "Forbidden Dress" or "Forbidden Lance" have stopped applying. Therefore, the monster affected by the effect of "Forbidden Dress" or "Forbidden Lance" remains on the field.^[3]

If there's one or more monsters with the same ATK as the monster with the lowest ATK under the control of the controller of "The Seal of Orichalcos", the opponent cannot target any of those monsters for an attack. Furthermore, if the controller of "The Seal of Orichalcos" only controls face-up monsters and they all have the same ATK, the opponent cannot target any monsters for an attack.^[4]
