Meria, Scholar of Antiquity

Artifacts as mana rocks is old news; artifacts as a repeatable card-advantage engine that costs nothing but a tap is the interesting reframe. The first ability turns any nontoken artifact into a green Llanowar Elves for a turn, which is fine ramp on its own. The second is the payload: two artifact taps convert into an impulse draw, exiling the top card and letting you cash it that turn. What makes this build coherent is that both abilities feed the same resource. Every permanent artifact you stick becomes fungible between ramp and impulse advantage, so a board of mana rocks, equipment, and utility trinkets is not just fixing but a churning card-selection machine. The nontoken clause is the constraint that keeps it from spiraling: Treasures and Clues can be sacrificed for their own effects but cannot tap for either of Meria's abilities, so the engine rewards durable artifacts you keep on the table rather than a one-shot token flood. That restriction pushes deckbuilding toward cheap, permanent artifacts you want anyway, and away from the ephemeral value that would otherwise make a repeatable free impulse draw obscene. It sits in the lineage of red-green ramp payoffs that want to convert a wide board into velocity, but the artifact axis gives it a different texture: this is an artificer who reads her library one page at a time, funded entirely by the machines already at her side.
