Slagstone Refinery (BRO-243) is an uncommon artifact from The Brothers' War. It triggers whenever it or another nontoken artifact you control goes to the graveyard or is exiled from the battlefield to create a tapped Powerstone token that taps for colorless mana usable only for artifact spells and other non-nonartifact costs. The card supports artifact-focused decks by converting artifact death or exile into repeatable mana sources for further plays and activations.
