Drudge Spell
A graveyard recycler dressed as a token engine, built on a converter that few enchantments of its era bothered with: it eats two creature cards from your graveyard to manufacture one regenerating Skeleton. The exchange rate is the tell. You are spending dead bodies as fuel, so the card rewards a board that has already traded and a graveyard that keeps refilling, turning attrition into a slow drip of indestructible-feeling blockers. The regeneration clause is what makes the Skeletons stick around through combat and most removal of the period, which is precisely why the second line exists. The leaves-the-battlefield clause is the structural counterweight: blow up the enchantment and every Skeleton token dies at once, unable to regenerate, so the whole army is keyed to the survival of a single two-mana permanent. That dependency is the design discipline holding the rate in check. Without it, a two-mana engine that converts spent creatures into a renewable wall of regenerators would be a genuine grind-out problem; with it, the opponent always has a clean answer that resets the entire investment in one shot. It is a study in tying a token swarm's fate to its source, a fragility-by-design pattern that later cards would reach for when they wanted token generators to carry an exploitable weak point rather than run away with the game.
