金屑石の精錬所 {4}

Notes and Rules Information for 金屑石の精錬所:

• Only the English version of a Magic card receives Oracle updates and errata. View this card in English. (Scryfall note)
• If Slagstone Refinery is put into a graveyard from the battlefield or exiled from the battlefield at the same time that one or more other nontoken artifacts controlled by the same player are put into a graveyard from the battlefield and/or exiled from the battlefield, its triggered ability will trigger once for each of them plus once for itself. (2022-10-14)
• 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." (2022-10-14)

• 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. (2022-10-14)
• 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. (2022-10-14)
