Trinket Mage

The restriction is the whole design: a tutor that reaches only the cheapest artifacts, the one-mana cogs built precisely to be fetched. That ceiling sounds limiting until you count what lives under it: Sol Ring and Mana Vault among the explosive mana rocks, equipment like Skullclamp, and a deep bench of utility pieces that almost guarantees the search finds something worth grabbing. What separates this from a raw, open-ended artifact tutor is that the selection comes welded to a body, and the body is the point as much as the search is. Rendering tutoring as an enters trigger rather than a spell changes the card's whole strategic axis: it can be blinked, bounced, and recurred, turning a one-shot fetch into a repeatable engine. A tutor you can run back would be dangerous if it pulled your best bombs, so the cheap-artifact clause is the brake on that loop, keeping it pointed at small cogs rather than format-warping rocks. The 2/2 also doubles as insurance: in the rare game where nothing in your library is worth finding, you still have a creature that blocks and chips. This is artifact selection at its most modular and durable. It trades the ceiling of a wide-open search for the floor of a body and the option to do it again, and it rewards shells assembled around finding a specific small piece rather than a single haymaker.
