Repurposing Bay

A tutor built on a ladder instead of a menu: each activation converts an artifact into one worth exactly one more mana, dropped straight onto the battlefield rather than into hand. The design borrows the transmute logic (fetch a card of a specific mana value) and welds it to a sacrifice engine that steps upward one rung at a time. That single-step constraint is what pays for putting the tutored card into play for free: you cannot leap from a Sol Ring to a game-ender in one crank, only from a two-drop to a three, a three to a four, up the curve piece by piece. The sorcery-speed lock closes the instant-speed window that would otherwise let this ambush blockers or flash in an answer, keeping it honest as a value engine rather than a combat trick. What makes the climb worth it is that the sacrificed artifact and the fetched one both matter: cheap tokens and expendable rocks become the fuel, and the shuffle that follows each search means it doubles as a way to churn a stale top of library. It rewards a board built as a staircase of artifacts at consecutive mana values, each one a stepping stone to the next, which is a narrower ask than a blind tutor but a more repeatable one.
