Scourge of Numai

The body is the giveaway: a 4/4 for with no evasion and no keyword was priced as a fair beater for its era, and the upkeep drain pays for whatever fraction of a mana it came in under. What makes the demon strange is what triggers the bleed. It does not punish you for casting it; it punishes you for not controlling an Ogre, which converts a generic body into a tribal incentive piece. This is an Ogre payoff wearing a Demon's type line. The clause turns a creature type that was, on its own, a pile of aggressive bears into a thing worth caring about, and waives a two-life-per-turn tax in exchange. The cleverness is that the cost is soft, not hard. You can run the Scourge with zero Ogres and simply eat the drain, treating it as a clock ticking against you rather than an unplayable card. Most drawback creatures of this shape impose a binary deckbuilding choice: control the named permanent or suffer for the whole game. This one lets each game decide whether the body is worth the upkeep, which is the quietly flexible part of the design. The Demon Spirit line is where the flavor seam shows: the upkeep loss reads as a spirit feeding on its controller, and the Ogre keeps it sated.
