A tutor that walks up the mana curve one artifact at a time. The activation reads like a chain: sacrifice a two-drop artifact, fetch a three, fetch a four off that, and so on, each step converting a cheap permanent already on the battlefield into a strictly more expensive one placed directly into play. The sorcery-speed restriction and the tap cost slow the engine to roughly one rung per turn, and that slow clock is the only thing keeping a repeatable put-onto-the-battlefield tutor from running away with the game the moment it resolves. What makes the ladder work is that it starts from the bottom: any mana rock or zero- and one-cost trinket becomes the seed, and the artifact you eventually deposit is pulled from your whole library rather than your hand, so a deck's expensive top-end never rots uncastable as long as you can spare something that costs exactly one less. This is white reaching for the top of an artifact deck's curve without paying the top-end mana, something the color almost never gets to do, and doing it through a fragile 2/2 body that telegraphs the plan and begs for a removal spell in response. The trade is deliberate: enormous selection and inevitability, gated behind a one-per-turn clock and a creature any opponent will happily kill before it takes a second step up the ladder.
