Iron Myrramp$0.86A two-mana mana creature that taps for mana immediately in the same role as a colorless accelerator. It adds colored mana instead of only {C}, which can be better in multicolor decks.
Silver Myrramp$0.41Same two-mana artifact mana creature role, but produces {U} instead of {C}. It is a functional analogue for decks that want cheap artifact ramp with color fixing.
Gold Myrramp$3.01A direct two-mana artifact mana dork like Manakin, with the same broad purpose of accelerating mana. It trades colorless output for white fixing.
Leaden Myrramp$1.80Same chassis as a two-mana artifact creature ramp piece. It provides black mana fixing, making it a close functional equivalent in black decks.
Copper Myrramp$0.99Another two-mana artifact mana creature that fills the same early-ramp slot. It produces red mana rather than only colorless.
Plague Myrramp$1.46Similar two-mana artifact creature that accelerates mana, with the added upside of infect in some contexts. It is a strong strict upgrade when you also value a mana dork body.
Burnished HartrampBudget$0.09A colorless artifact creature ramp option that serves the same broader role of increasing mana, though through a different sacrifice-based line. It is slower but provides actual land ramp.
Fellwar Stoneramp$1.91A cheap colorless artifact ramp piece that plays the same role of fixing or accelerating mana in multiplayer decks. It is not a creature, but it is a common functional substitute for two-mana ramp.
