Undead Servant
A build-around that asks for the most counterintuitive deckbuilding instinct in the game: draft, buy, or run as many copies of one mediocre common as you can stand. The trigger counts copies sitting in the graveyard, so the payout runs backward from how tribal and recursion cards usually work. Most such payoffs want earlier copies on the battlefield or want variety in the yard; this one wants its predecessors buried, and the engine only fires after the first few have died, been discarded, or been milled. The opening cast resolves with an empty trigger and leaves a 3/2 on the board, because nothing has hit the graveyard yet; the second arrival makes a token, the third makes two, and a deck running a full set turns the last copy into a wide swing of 2/2 Zombies that all came from a single card slot. It sits with a handful of self-referential commons whose ceiling and floor are set by redundancy rather than rate: deliberately weak in isolation, deliberately scalable when a deck commits to four-of-itself plus the discard, mill, or sacrifice effects that feed the yard. The graveyard requirement is the cost that pays for the wave, since the Zombies arrive in proportion to how much earlier work the deck has already done.
