Arcum's Whistle⁣ - Ice Age⁣ (Uncommon)

Arcum's Whistle is a three-mana artifact from Ice Age that allows you to force a non-Wall creature controlled by the active player to attack, unless they pay its mana value. This can disrupt your opponent's plans by pushing their creatures into combat, potentially sacrificing them if they don't pay up. It works well in decks that focus on controlling the board and punishing opponents for not being able to protect their key creatures. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
