Candles of Leng

A draw engine with a built-in punishment for redundancy: every activation gambles that the next card off the top is not something you already buried. The activation cost is the giveaway. Four mana plus the tap means this was never meant to chain into an early explosion; it is a slow, repeatable card-advantage faucet for a board state that has already stabilized. The clever bit is how the failure case still moves the game forward, thinning the duplicate into the graveyard so the next look comes up cleaner. That self-correcting loop rewards a library built on singletons, an engine that ages into a niche rather than a fixture: it asks you to mill yourself selectively in exchange for filtered draws, and it asks patiently, four mana a turn for a single card when the names line up. The graveyard-matching clause gives it a memory few artifacts have; it cares not just about what you draw but about what you have already drawn, turning the discard pile into a constraint on the engine itself. The more diverse the nameplate count in your deck, the more activations end in a draw rather than a mill, so its efficiency climbs the longer a game stalls and the wider the spread of names in your library. A quiet rewards-the-grind artifact that asks for board parity and singleton diversity as its entry fee.
