Sorin the Mirthless

The plus ability is the honest core of the design: card advantage priced in life, scaled to whatever you find. Reveal a land and you pay nothing; reveal your finisher and you bleed for it. That self-imposed tax keeps a mono-black walker drawing every turn without running away with the game, and it fits Sorin's long history of treating life as a spendable resource. It is also the only ability here that adds loyalty, which frames the rest of the kit: the minus makes a 2/3 flier with lifelink, a body that guards the walker while quietly refunding the life the plus keeps spending. So the two minus abilities split the labor rather than chain into each other, one protecting the engine and stabilizing the life total, the other cashing everything out. That ultimate is the payoff: 13 damage and 13 life, enough to end most games in one activation, and it arrives from four starting loyalty plus three plus-one turns rather than the long climb bigger walkers demand. What separates this Sorin from his earlier incarnations is compression: previous versions spread their attention across lifelink, tokens, and reach on heavier frames, while this one folds the whole vampire-lord kit (draw, drain, flying lifelinker, life swing) into four mana that asks only for a little self-inflicted damage in exchange for never running dry.
