Rulings
- This effect targets 1 face-up card on the field. It targets that card continuously throughout the turn.
- Paying 500 Life Points is a cost, not an effect. It cannot be negated by "Royal Decree."
- If "Seal of Wickedness" targets itself, it will be negated for 1 turn. You can flip "Seal of Wickedness" and activate its effect in the same Chain.
- If "Seal of Wickedness" is destroyed, removed from the field, or negated while it is negating a card, its effects will no longer be applied and the selected card will no longer be negated.
- The effect to negate a card starts a Chain in the Standby Phase. It is a mandatory effect.
