Arcane Proxy (BRO-319 foil) is an Artifact Creature — Wizard from The Brothers' War with the Prototype keyword that can be cast for an alternate 2/1 prototyped cost. When it enters the battlefield after being cast, it exiles an instant or sorcery from your graveyard with mana value less than or equal to its power and copies that card, allowing you to cast the copy without paying its mana cost. Its role is value generation and graveyard recursion, enabling one-shot access to spells for tempo or combo lines.
