Blood Moonutility$8.90It turns lands into a basic land type, dramatically changing mana bases and utility lands. While it affects all nonbasic lands instead of just one, it serves a similar land-disruption role.Sea's Claimutility$0.16This is the closest direct analogue: a cheap blue land-aura that turns a land into an Island. It lacks the cantrip, but it fulfills the same land-denial function.Tidal Warriorutility$0.16It can repeatedly turn lands into Islands, enabling similar color denial and islandwalk synergies. It’s more flexible over time, though it requires a creature and tap activation.Quicksilver Fountainutility$5.80Like Spreading Seas, it messes with land types and can interfere with mana development over several turns. It is slower and broader in scope, but it creates similar Island-based disruption.Convincing Mirageutility$0.16A cheap blue land Aura that changes a land’s type, directly competing as a mana-denial enchantment. It does not draw a card, but it is one of the closest functional substitutes.Dream ThrushutilityBudget$0.11It can turn lands into any basic land type, including Islands, which can disrupt opposing mana or enable synergies. The effect is creature-based rather than an Aura, but the function overlaps.Magus of the Moonutility$4.89This is a stronger land-type disruption piece that shuts off many mana bases by turning lands into Mountains. It fills the same disruptive niche, though in red and with a different conversion target.Lush Growthutility$0.12It changes a land into a basic land type and replaces itself with a card, making it a functional cousin to Spreading Seas. It’s often used for fixing or enabling domain instead of denial.
