Goblin Warrens

A self-fueling token engine with a net gain of exactly one Goblin per activation: feed it two, get three back, and pay enough mana that the loop is a slow snowball rather than free value. That arithmetic is the whole design tension. With no sacrifice payoff attached, three small bodies for the price every turn is a grindy and unspectacular plan; the card is built to be a piece, not an engine in isolation. Its real ambition was a payoff that turns the surplus into damage or drain, the kind of outlet that converts a marginal token-replacement rate into a kill. The design experiments with the idea that a tribe could carry its own self-replicating resource, a sacrifice-and-replace pump that predates the dedicated sacrifice outlets which would later make this kind of body-recycling lethal rather than merely tidy. The constraint that defines it is the activation cost itself: because every use eats two Goblins, the Warrens cannot bootstrap from nothing and cannot rebuild after a board wipe leaves you with no fodder to feed it. It only compounds an advantage you already have, widening a board into a wider one. That dependence on a surviving population is exactly why Goblin token strategies have always looked back at it as a flavorful foundation that asks for support, not a standalone engine that supplies it.
