Diviner's Lockbox⁣ - Core 2020⁣ (Uncommon)⁣ [225]

Diviner's Lockbox is a four-mana artifact from Core Set 2020 that allows you to name a card and then reveals the top card of your library. If the revealed card matches the name you chose, you can sacrifice the Lockbox to draw three cards, which provides significant card advantage. This card works well in decks that focus on card selection and manipulation, as it rewards you for knowing your library and can help you dig for key pieces, but keep in mind it can only be activated as a sorcery. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
