Ghoulcaller's Harvest

The graveyard-as-fuel token maker, built around a resource most decks are actively trying to fill anyway. The math is the design: X counts half your dead creatures rounded up, so this scales with a self-mill or sacrifice engine that has already been feeding the yard for other reasons, then converts that surplus into a wide board on a two-mana sorcery. The decayed keyword is what keeps the payout honest. These Zombies can't block and eat themselves after one swing, so the tokens are explicitly disposable: a single alpha strike, or a pile of sacrifice fodder for aristocrat triggers, rather than a lasting army. That fragility is what lets the card be priced where it is, and it reframes the tokens from board presence into ammunition. The flashback clause doubles the payout without doubling the cost of holding the card: it lets you cast the spell again from the graveyard, and because it only counts creature cards in the yard rather than consuming them, the buyback second casting tends to arrive when the graveyard has grown larger and pays out bigger. Two spells from one card, both keyed off the same growing resource, both spitting out fodder that wants to die: this is a design that treats the graveyard less as a place to reanimate from and more as a quantity to cash in.
