II — Choose two target players. Until your next turn, each creature they control attacks the other chosen player each combat if able.
III — This Saga deals X damage to any target and X damage to any other target, where X is the number of artifacts you control.
（于此传纪进战场时及于你抓牌步骤后，加一个学问指示物。到III后牺牲之。）

虽然兄弟之战系列中所有能派出魔力石衍生物的牌，派出的都是已横置的魔力石衍生物，但「横置进战场」并不属于该衍生物预定义内容的一部分。特别一提，如果你派出一个为魔力石衍生物复制品的衍生物，则该衍生物不会是横置进战场。
Although all the cards in The Brothers' War that create Powerstone tokens create a tapped Powerstone token, entering the battlefield tapped isn't part of the token's definition. Notably, if you create a token that is a copy of a Powerstone token, the token copy won't enter the battlefield tapped. -

只要是非神器咒语以外的东西，你就可以用魔力石衍生物产生的这份{无}来支付。这包括支付用于起动神器或非神器永久物之异能的费用，支付守护费用，等等。
You can use the {C} added by a Powerstone token on anything that isn't a nonartifact spell. This includes paying costs to activate abilities of both artifact and nonartifact permanents, paying ward costs, and so on. -

魔力石衍生物是一种预定义衍生物。每个此类衍生物都具有「魔力石」此神器类别，且具有异能「{横置}：加{无}。此法术力不能用来施放非神器咒语。」
Powerstone tokens are a kind of predefined token. Each one has the artifact subtype "Powerstone" and the ability "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell."
