Talisman of Curiosityramp$0.37Produces either blue or green mana immediately, filling the same two-color fixing role as a cheap mana rock. It also costs the same amount and is often a strict upgrade because it can tap for mana without needing an extra activation cost.
Izzet Signetramp$1.59Shares the same signet cycle structure with a 2-mana artifact that filters mana into two colors. It’s a close functional template if you want a similar early-game fixer in another guild.
Selesnya Signetramp$0.40Another 2-mana signet-style artifact that turns one mana into two allied colors. It functions nearly identically as a reliable early fixer in multicolor decks.
Dimir Signetramp$0.72Same signet cycle and same two-mana mana-fixing role, differing only in color pair. It’s one of the closest functional equivalents available.
Arcane Signetramp$0.64A premium 2-mana artifact mana rock that fixes into your commander’s colors immediately. It’s broadly stronger than Simic Signet because it produces the relevant colors without requiring an activation payment.
Mind Stoneramp$0.31A generic 2-mana artifact ramp piece that accelerates mana in the same early-game slot. It doesn’t fix colors, but it serves a similar role as an efficient budget mana rock.
Fellwar Stoneramp$1.91A 2-mana artifact that often produces the colors you need in multiplayer, making it a common two-color fixing substitute. It overlaps well with the role of inexpensive mana smoothing.
Prismatic Lensramp$0.38A 2-mana artifact that filters mana and helps fix colors in a way similar to a signet. It’s a budget-friendly analogue, though a bit less efficient than Simic Signet in some board states.
