カード裁定
2008/10/01
原文You put the creature card onto the battlefield even if you can't sacrifice Helm of Obedience (because it's left the battlefield by the time its ability resolves, for example).
2008/10/01
原文If an effect like that of Leyline of the Void prevents cards from being put into your opponent's graveyard, the process described in the first sentence of Helm of Obedience's effect will never stop. Your opponent's entire library will be exiled, even if X is 1.
