The one-mana artifact that fixes a land drop without ever going dead in the late game. The failure clause does the design work: it digs through the top five for a land, but when there is no land to find, it hands you a card off the top instead. That toggle keeps it honest against the strict land-tutor problem; you never crack it to reveal five spells and get nothing. The cost is friction. It taps, it wants a mana on activation, and it demands you sacrifice it, so the smoothing you buy is deferred and paid in a full turn's tempo. That places it firmly in the deck that treats early turns as setup rather than pressure: a slow midrange or control shell that would rather spend a mana and a card slot for a better shot at a land drop later than gamble on flooding or screwing. The bottom-in-random-order clause matters too, denying the information a scry or surveil would leave behind; you learn which five cards were not on top, then lose track of them entirely. It is a modest engine piece dressed as fixing, built for the archetype that values consistency over raw card advantage and can afford to spend a turn making its draws behave.
