顯化數問 - 魔法風雲會

http://community.wizards.com/forum/rules-theory-and-templating/threads/4180881

這邊討論了顯化＆替代費用以及衍生問題，以下是重點摘要

1. 替代費用會說它是否只在施放咒語時有效，如果沒說，那在任何時候都有效。

2. 所有跟替代費用有關的關鍵字(返照，超載等等)，都限定只在施放咒語時有效。
只要設計團隊不想自找麻煩，未來也會一直如此。

3. 下列牌的替代費用在任何時候都有效：

白曙光信使 http://magiccards.info/5dn/en/7.html 以及其快樂的夥伴們
天帷鐮腕獸 http://magiccards.info/ne/en/118.html
藤蔓樹靈 http://magiccards.info/mm/en/284.html
廢品泰坦 http://magiccards.info/ala/en/84.html
異特龍騎兵 http://magiccards.info/cs/en/101.html
死門惡魔 http://magiccards.info/m11/en/92.html
伊莫庫之手 http://magiccards.info/roe/en/5.html
迪銳奇 http://magiccards.info/mm/en/133.html

如果只在施放咒語時有效，異能上面會說，例：
笑面貓憲太郎 http://magiccards.info/bok/en/13.html
You may pay {X} rather than
pay the mana cost for Samurai spells you cast, ...

五陽護手 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.

最後一個問題，顯化付的費用到底是什麼？
討論串中所有人都認定是魔法力費用無誤，但光這樣口說無憑，必須請出正式規則：

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.)

顯化過程中你要做的確實是一個「支付魔法力費用」的動作。
如果某張牌說你可以鬼吼鬼叫並活活挖出三個祭品的心臟，以作為替代費用的話，
那麼除了一些遊戲以外的糾紛外，你毫無疑問地可以這樣做。
