Simic SignetrampBudget$0.21Same two-mana signet-style mana rock with the same activated filtering pattern, just in different colors. It serves the same early fixing role in multicolor decks.
Dimir Signetramp$0.72Same functional template as Azorius Signet: a 2-mana artifact that turns 1 generic mana into two colored mana. It is a direct parallel signet for different color pairs.
Boros Signetramp$0.79Same signet cycle card and identical activation structure, providing two-color fixing for two-mana artifact decks. It fills the same ramp and color-fixing slot.
Selesnya Signetramp$0.40Same role and rules pattern as Azorius Signet, just producing a different pair of colors. It is one of the closest functional equivalents available.
Talisman of Progressramp$0.39Similar early-game color fixing artifact for white-blue decks, coming down for 2 mana and producing colored mana immediately. It trades the signet activation for painless or damage-based output.
Azorius CluestonerampBudget$0.09A 2-mana Azorius fixing rock that fills the same color-identity slot, though it is slower and later can be sacrificed for a card. It is a budget-friendly functional substitute.
Talisman of Dominanceramp$4.04Another 2-mana mana rock with immediate access to colored mana and strong early fixing. While not Azorius-colored, it plays the same role in two-color and multicolor shells.
Fellwar Stoneramp$1.91A cheap two-mana artifact that commonly taps for colored mana in multiplayer and early fixing. It is one of the best broad replacements for a signet-style mana rock.
