http://community.wizards.com/forum/rules-theory-and-templating/threads/4180881 这边讨论了显化＆替代费用以及衍生问题，以下是重点摘要 1. 替代费用会说它是否只在施放咒语时有效，如果没说，那在任何时候都有效。 2. 所有跟替代费用有关的关键字(返照，超载等等)，都限定只在施放咒语时有效。 只要设计团队不想自找麻烦，未来也会一直如此。 3. 下列牌的替代费用在任何时候都有效： 白曙光信使 http://magiccards.info/5dn/en/7.html 以及其快乐的夥伴们 天帷镰腕兽 http://magiccards.info/ne/en/118.html 藤蔓树灵 http://magiccards.info/mm/en/284.html 废品泰坦 http://magiccards.info/ala/en/84.html 异特龙骑兵 http://magiccards.info/cs/en/101.html 死门恶魔 http://magiccards.info/m11/en/92.html 伊莫库之手 http://magiccards.info/roe/en/5.html 迪锐奇 http://magiccards.info/mm/en/133.html 如果只在施放咒语时有效，异能上面会说，例： 笑面猫宪太郎 http://magiccards.info/bok/en/13.html You may pay {X} rather than pay the mana cost for Samurai spells you cast, ... 五阳护手 http://magiccards.info/5dn/en/123.html You may pay {W}{U}{B}{R}{G} rather than pay the mana cost for spells that you cast. 最後一个问题，显化付的费用到底是什麽？ 讨论串中所有人都认定是魔法力费用无误，但光这样口说无凭，必须请出正式规则： 701.31b Any time you have priority, you may turn a manifested permanent you control face up. This is a special action that doesn't use the stack (see rule 115.2b). To do this, show all players that the card representing that permanent is a creature card and what that card's mana cost is, pay that cost, then turn the permanent face up. The effect defining its characteristics while it was face down ends, and it regains its normal characteristics. (If the card representing that permanent isn't a creature card or it doesn't have a mana cost, it can't be turned face up this way.) 显化过程中你要做的确实是一个「支付魔法力费用」的动作。 如果某张牌说你可以鬼吼鬼叫并活活挖出三个祭品的心脏，以作为替代费用的话， 那麽除了一些游戏以外的纠纷外，你毫无疑问地可以这样做。 --
