Slagstone Refinery

Artifact

Whenever this artifact or another nontoken artifact you control is put into a graveyard from the battlefield or is put into exile from the battlefield, create a tapped Powerstone token. (It's an artifact with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.")

Slagstone Refinery card art
Slagstone Refinery turns every scrap token into a Treasure, which means artifact-sacrifice loops that would otherwise cost mana start generating it instead. Farid, Enterprising Salvager and Ashnod, Flesh Mechanist both want exactly this — an enchantment that converts fodder into fuel without taking up a creature slot.

Slagstone Refinery is a Commander card — the effect is too slow and too incremental to compete in Modern or Legacy, where sacrifice synergies need to close games in the first few turns rather than build an engine. In Pioneer the same problem applies; storm-style artifact loops have faster, more redundant payoffs available. Commander is where Slagstone Refinery earns its slot, specifically in artifact-sacrifice decks that generate lots of token fodder and want mana acceleration baked into their loop rather than grafted onto it.

Price Context

Current price

$0.14 bulk tier

At $0.14, Slagstone Refinery is bulk — grab a copy without thinking about it. Bulk enchantments with niche combo applications rarely spike unless a new commander pushes them into mainstream lists, so don't expect it to move, but at this price the question is just whether it fits your deck.
