Sliversmith

An artifact creature that builds artifact creatures, dressed up in Spellshaper clothing. The Spellshaper class was a future-leaning experiment in giving creatures one repeatable spell-like activation, usually paid for with a card from hand, and most of them mimicked an existing instant or sorcery. This one mimics nothing in particular: it converts spare cards into a slow trickle of Metallic Sliver tokens, the most deliberately bare-bones Sliver ever printed, a 1/1 with no abilities of its own that exists purely to inherit whatever the rest of your board is handing out. That is the whole pitch, and it explains why the card was built the way it is. A Metallic Sliver alone is a worse Memnite; a Metallic Sliver under a board of Sliver lords is a 4/4 with shroud, regeneration, and three keywords. Sliversmith trades cards you don't need for bodies that the tribe's collective anthem effects make worth far more than the discard cost suggests. The friction is real: one mana and a card per token is a steep tax to pay one at a time, and the 1/1 frame and slow clock mean this is an engine for grinding boards wide, not a fast clock. It sits at the intersection of two of the game's most build-around mechanics (Spellshaper activation and Sliver synergy) and commits fully to the second, asking you to already have the payoff in play before the card means anything.
