Emeria, the Sky Ruin - Commander: Secrets of Strixhaven (Rare) [SOC-368]

Emeria, the Sky Ruin is a utility land from the Secrets of Strixhaven Commander release that taps for white mana and enters tapped like most lands of this type. Its real value comes from the upkeep trigger: once you control seven or more Plains, you can return a creature card from your graveyard to the battlefield every turn. This rewards mono-white or Plains-heavy decks that lean into land-fetching and basic land synergies, since hitting that seven-Plains threshold takes dedicated deckbuilding around fetching or ramping basics specifically. The payoff scales well with big creatures or ETB effects, letting you rebuild your board state turn after turn once the condition is met, though the requirement makes it a slow engine rather than an immediate source of value.
