Ashnod's AltarrampBudget$13.70Provides the same core function of converting a creature or artifact into four colorless mana, though as an activated sacrifice outlet instead of a death trigger.
Krark-Clan IronworksrampBudget$15.21A classic colorless mana conversion piece that turns artifact deaths into {C}{C}, making it a close combo-adjacent analogue for artifact-based mana generation.
Priest of TitaniarampBudget$5.07Like Su-Chi, it can generate a burst of mana from board state, but it scales with Elves rather than dying for a one-shot payout.
SacrificerampBudget$10.19A direct functional descendant of the old-style death-to-mana effect, turning a dying creature into a large burst of colorless mana.
Burnt OfferingrampBudget$2.95Converts a creature into a large amount of black mana, similar to Su-Chi's death trigger in that it banks a creature body into mana.
Ashnod's TransmograntutilityBudget$4.83A colorless artifact that interacts with creatures and mana in a similar old-school artifact-combo space, though it is more of a support piece than a direct mana engine.
Treasure VaultutilityBudget$1.07Not a creature, but it gives a colorless mana sink that can later convert into a burst of artifacts/copyable resource, fitting the same colorless ramp shell in artifact decks.
Metalworkerramp$152.18Another colorless artifact creature that can generate a huge burst of mana, often exceeding Su-Chi when built around artifact density.
