節錄
Checks the actual printed cost on the creature card, and is not affected by things which allow you to play the spell for less, such as with the Emerald Medallion. [D'Angelo 1997/10/20]
減費用的，不受影響，仍然視牌面上實際印出施放費用，因此不能這樣用
Any penalty costs such as Gloom still need to be paid. [D'Angelo 1997/12/29]
額外會增加費用的還是要付
You cannot use Aluren when playing a creature using another alternate means, such as the Morph ability. [WotC Rules Team 2002/10/01]
morph之類的另外方式施放生物的也不能用於誘魔法陣
You are still casting the creature spells. [Duelist Magazine #23, Page 22] So they can be countered. [D'Angelo 1997/11/07]
另外藉由誘魔法陣而施放的生物仍視為"play"，因此可以反擊
