Ashnod's AltarrampBudget$13.70Converts a creature into a burst of colorless mana, making it one of the closest functional analogs to Su-Chi's death trigger. It is more efficient because it can be used repeatedly and at instant speed.
Krark-Clan IronworksrampBudget$15.21Another classic artifact-based mana engine that turns dying artifacts into colorless mana. It is broader than Su-Chi because it works with any artifact, not just itself.
Myr RetrieverutilityBudget$2.31Artifact creature that replaces itself when it dies, creating resource value from a dying body like Su-Chi does with mana. It is a different reward, but fills a similar sacrifice/value role in artifact decks.
Junk DiverutilityBudget$0.30Very similar to Myr Retriever, rewarding artifact death with card recursion. It is a strong budget value creature for sacrifice shells, though it provides recursion instead of mana.
Workshop AssistantutilityBudget$0.17Artifact creature that returns a card when it dies, occupying the same general slot of a disposable artifact body with death value. It is slower than Su-Chi but serves similar graveyard/value plans.
Pilgrim's EyeutilityBudget$0.16Colorless artifact creature that provides value on entering or leaving the battlefield and is commonly used in artifact decks. It is not a mana burst, but it is a similar utility body at a comparable cost.
Solemn SimulacrumrampBudget$0.23A staple colorless-value creature that generates advantage when it dies, similar to Su-Chi's death-trigger payoff. It is stronger overall, trading mana burst for land ramp and card draw.
Burnished HartrampBudget$0.09A colorless creature that can be sacrificed for mana acceleration, echoing Su-Chi's role as a body that turns into resources. It is slower, but the mana production is real and repeatable in sacrifice decks.
