Card Rulings:Dark Room of Nightmare


 * A cost is not damage so this card's effect does not apply against "Chain Energy", or costs for "Imperial Order", etc.

Other Rulings

 * [Re: Barrel Behind the Door] If you re-direct damage to your opponent using "Barrel Behind the Door", and you have "Dark Room of Nightmare" on the field, then "Dark Room of Nightmare" inflicts 300 more damage.


 * [Re: Magical Thorn] Even though "Magical Thorn" does damage per card discarded, it deals the damage as one lump sum for effects like "Dark Room of Nightmare".
