Card Rulings:Ghostrick Mansion

OCG Rulings

 * Regardless of which player activated "Ghostrick Mansion", its effect applies to all monsters on the field. Therefore, if an opponent's "Ghostrick Stein" inflicts battle damage, even if you are the player who activated "Ghostrick Mansion", the battle damage you take from "Ghostrick Stein" is not halved. Similarly, if a "Crane Crane" you control inflicts battle damage to your opponent, that battle damage is halved.


 * The effect of "Ghostrick Mansion" is applied to the monsters each player controls. Regardless of which player activated this card, "Monsters cannot attack face-down Defense Position monsters, but can attack directly if all monsters their opponent controls are face-down Defense Position.". Furthermore, if each player controls "Ghostrick Mansion", the "All effect damage, and battle damage inflicted by monsters other than "Ghostrick" monsters, is halved." effect is only applied once and the battle damage is halved normally. (The damage is not reduced to 1/4th.)
