Cloud of Faeriesramp$0.49A cheap creature that reduces the cost of your spells by effectively refunding mana through untapping lands, helping accelerate tribal or low-curve decks. It plays a similar tempo-support role in decks that want to chain multiple spells early.
Heartless Summoningramp$0.73Reduces the cost of your creature spells, enabling faster deployment of a creature-heavy strategy. It is a broader, more powerful cost reducer than Frogtosser Banneret, though it affects your creatures' size.
Bontu's Monumentramp$3.70Provides ongoing cost reduction for black creature spells, especially useful in decks built around swarming cheap creatures. It also adds incidental drain, making it a strong black tribal support piece.
Herald's Hornramp$4.65A tribal cost reducer that discounts your creature spells of the chosen type, making it a close functional analog in tribal decks. It also provides card advantage through the top-card reveal ability.
Urza's Incubatorramp$17.46One of the strongest tribal cost reducers, cutting two mana from spells of the chosen creature type. It fills the same role of accelerating creature-heavy tribal decks, just at a higher mana value.
Baral, Chief of Complianceramp$13.68A creature-based cost reducer that discounts your noncreature spells by one, functioning as a similar tempo enabler in spell-heavy decks. While not tribal, it occupies the same low-cost support slot.
Jace's Sanctumramp$0.67Reduces the cost of your instants and sorceries and rewards you for casting them, serving as a comparable spell-acceleration engine. It is slower, but often stronger in dedicated spell decks.
Stenn, Paranoid Partisanramp$0.18A low-cost creature that reduces the cost of historic spells, offering a similar early-game discount engine. It is narrower in what it helps cast, but fits decks seeking cheap setup and acceleration.
