Forensic Gadgeteer

Two engines welded to one body, and the seam is where the deck gets built. The first half converts every artifact spell you cast into a Clue, turning an artifact-dense curve into a stream of card advantage that also feeds anything caring about artifacts entering: sacrifice fodder, metalcraft-style counts, treasure-adjacent loops. The second half is the quieter of the two but the one that scales without limit, shaving a mana off every artifact activation you control. That reduction is capped so it can never make an ability free, which is the specific discipline holding the card back from breaking: a machine that would trivialize any activation costing a single mana still has to pay one. Where the cost reduction earns its keep is on artifacts you tap repeatedly, the ones that would otherwise strangle your mana over a long game. Neither ability closes a game alone; the body is a modest 2/3 that blocks and little else. What the card offers is throughput, a role white-blue and mono-blue artifact shells have wanted since the earliest affinity experiments: something that rewards playing many cheap artifacts by paying you in cards on the way in and discount on the way out. The Clue engine wants width; the reduction wants depth. Build for both and the two halves stop being separate lines on a card and start being the same turn.
