Sheoldred, the Apocalypse

Two triggers that read like a mirror but are built to point the same way: you gain when you draw, they bleed when they do. That asymmetry is the whole idea. Card advantage is the resource black has always bought with life, and here that bargain gets inverted and shipped across the table: drawing cards is not optional in modern Magic, so every opponent's draw step, every cantrip they run to dig out of trouble, costs them two life while your own draws top you off. She taxes the most fundamental action in the game, and she taxes it in one direction only. The body is what makes that engine stick. Five toughness climbs out of the reach of most burn and combat math that would clear a four-drop, deathtouch turns attacking into her into a losing trade, and the ground she holds is the ground on which the life drain ticks even when she is not attacking. Black's Praetors have each modeled a facet of the color's identity; this one distilled its oldest transaction (knowledge for life) and reassigned the cost onto everyone else. Four mana buys a wall the opponent cannot profitably attack, a life-total cushion, and a clock that runs on the enemy's own habits. The effect looks even because it names both players, but it never was: the deck built around her draws on purpose while the opponent draws on schedule, and only one of them has to lose life to keep playing the game.
