Corpsehatch

Removal that pays you back, but in the currency of the era it was built for. Five mana to destroy a nonblack creature is a soft rate on its own; the spawn are what shift the math. Two tokens that each crack for one colorless mana mean the spell effectively refunds two mana on a future turn, or feeds whatever wants bodies to throw away: a sacrifice outlet, a Devour cost, the opening payment on something far bigger than the creature you just killed. The "nonblack" clause is the price of admission, narrowing the target so the spell stays honest against the decks most likely to share its color. That ramp-into-removal coupling is the design idea worth noting: it treats killing a creature and building toward a haymaker as the same turn's work, rather than asking you to spend a turn on each. The spawn don't make Corpsehatch fast; they make it patient, the kind of removal that buys time and then spends what it bought on the threat you actually want to cast. Read as a clean kill spell it looks overpriced. Read as removal stapled to a two-mana down payment, it earns the cost back on the turn after, setting up the haymaker the kill spell alone never could.
