Ancient Denutility$3.32Artifact land that fixes mana in white and shares the artifact synergies. It has the same tapped-less utility as a dual artifact land, though it only produces one color.
Great Furnaceutility$4.26Artifact land in the same Mirrodin cycle that supports artifact count and taps for a single color. It fills a very similar deck-building slot in red artifact shells.
Treasure Vaultutility$1.07Colorless artifact land that contributes to artifact synergies and can convert mana into Treasure tokens. It plays a similar utility-land role in artifact-heavy decks.
Cave of the Frost Dragonutility$0.56Manland that enters untapped and provides a resilient, color-producing land slot in white-based decks. It is a functional mana source with late-game utility, though not an artifact.
Den of the Bugbearutility$4.59Red utility land that can become a threat while still occupying a land slot in aggressive decks. It serves a similar role of providing mana plus additional value.
Sacred Foundryutility$16.14Fast Boros dual land that produces either color and can enter untapped at a life cost. It is the closest high-end color-fixing upgrade for red-white decks.
Clifftop Retreatutility$0.36Budget Boros dual that fixes red and white mana in the same color pair. It is a simple functional replacement for two-color mana bases, though it is not an artifact land.
Inspiring Vantageutility$10.92Efficient Boros dual for early game fixing, especially in aggressive decks. It offers similar color access with better speed, but no artifact synergies.
