Urborg, Tomb of Yawgmothutility$51.80It strongly interacts with Swamps by turning every land into a Swamp, enabling many of the same swamp-based synergies and land manipulation lines. While it does not animate lands, it changes the same land type environment that Kormus Bell cares about.
Night of Souls' Betrayalutility$1.73A classic anti-token and toughness-reduction artifact-like board control piece that pairs with Kormus Bell by killing the animated Swamps outright. It serves a similar disruptive role in creature-based land lock decks.
Living Planeutility$184.42This is the closest functional cousin: it turns all lands into 1/1 creatures while remaining lands. It affects all lands instead of just Swamps, making it a broader and often more powerful version of the same animation effect.
Blood Moonutility$8.90It attacks mana bases by changing nonbasic lands into Mountains, functioning as a land-hate piece in the same disruptive space as Kormus Bell. It does not animate lands, but it is frequently used in similar prison-style strategies.
Magus of the Moonutility$4.89A creature version of Blood Moon that punishes greedy mana bases and fits the same prison shell. Like Kormus Bell, it creates a persistent rules-changing effect that warps lands on the battlefield.
Convincing MirageutilityBudget$0.16It changes a land's basic land type, which can be used to redirect or disrupt mana production in a way that overlaps with land-type manipulation themes. While much narrower, it occupies a similar niche in land-hate and type-changing strategies.
Quicksilver Fountainutility$5.80This artifact gradually changes lands into Islands, providing a comparable long-game land-type transformation effect. It is another colorless artifact that messes with lands over time, though in a very different direction.
Retreat to Coralhelmutility$5.46It can repeatedly untap lands or tap down creatures and lands via landfall synergies, which is useful in land-based control/combo shells. While not a direct replacement, it often appears in decks built around unusual land interactions.
