Eldrazi Monumentutility$7.40Not a mana engine, but it often occupies a similar slot in black sacrifice/discard decks by turning expendable resources into a powerful board advantage. It’s a resilient colorless finisher that supports the same kind of grindy shell.
Bone ShardsremovalBudget$0.21Uses discard or sacrifice as part of its cost, making it a natural fit for decks that generate value from pitching cards. It’s efficient interaction for black decks that can spare resources.
Aphetto Alchemistutility$1.79A cheap utility creature that converts board resources into repeatable mana-adjacent value in combo shells. While not black, it fills a similar role as an engine piece that can enable degenerate lines.
Ashnod's Altarramp$13.70A classic sacrifice-based mana engine that turns expendable creatures into colorless mana. It serves a similar combo role as a resource-conversion engine, though it uses creatures instead of cards.
Altar of Dementiautility$19.67Another outlet that converts spare board resources into a strong combo payoff. It’s commonly used alongside graveyard and sacrifice plans in the same decks that want Skirge Familiar-style engines.
Phyrexian Reclamationcard_advantage$3.56A black value engine that turns cards and life into recurring advantage, helping grind through resources the way Skirge Familiar does in discard-heavy decks. It supports the same attrition/combo game plan.
Crypt Ghastramp$11.13A black mana-doubling engine that fills a similar role in big-mana black decks. It accelerates you toward large spell turns like Skirge Familiar can, though it is less combo-centric.
Desecrated Tombutility$1.49A grindy value piece for decks that repeatedly discard or recur creatures, creating incremental advantage from resource loops. It pairs naturally with black engines that want to convert graveyard movement into pressure.
