Entering the battlefield tapped, it allows you to surveil 1, letting you look at the top card of your library and choose to put it into your graveyard. This ability is valuable for decks that leverage graveyard mechanics, as it can help set up future plays while providing mana flexibility. It fits well in control or self-mill strategies where card selection and mana consistency are crucial. However, its requirement to enter tapped can be a drawback in fast-paced games. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.\n\u003c!-- AI-SEO END --\u003e","brand":"Vault of Cards | Magic: The Gathering Singles | UK MTG Shop","offers":[{"title":"English \/ Near Mint \/ Normal","offer_id":44059342700679,"sku":"PZA20-45458229","price":8.89,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0276\/6900\/4423\/files\/19545db3-8be5-41e5-8d13-dec4f96fe624.jpg?v=1776279899","url":"https:\/\/vaultofcards.co.uk\/products\/undercity-sewers-teenage-mutant-ninja-turtles-source-material-cards-mythic-20-873450","provider":"Vault of Cards","version":"1.0","type":"link"}
