Crowded Crypt

A mana rock that keeps a ledger of your dead. Ramp artifacts usually ask nothing of the board beyond the mana they tap for, but this one turns the incidental attrition of an aristocrats deck into stored value: every creature you control that dies feeds a counter, and the counters cash out later as an army. The design tension is the delay. You pay three up front for a black source, then wait for bodies to fall, then pay six more to convert the pile into decayed Zombies, tokens that swing once and are gone. That decayed clause is the pressure valve. Without it, a corpse-counting rock that spat out permanent blockers would snowball a sacrifice engine past the point of interaction; because the tokens cannot block and sacrifice themselves after attacking, the payoff is a one-shot alpha strike rather than a standing board, which keeps the whole loop honest. It rewards patience without rewarding a stall: sit on it too long and you have only ramped, activate it and you have converted a graveyard's worth of history into a single reckless attack. The result reads less like a value engine and more like a slow fuse, a rock that funds itself on your losses and asks you to spend them all at once.
