Sorin, Vengeful Bloodlord

Reanimation is the headline, but the turn-restricted lifelink blanket is what holds the plan together. The minus is scaled recursion: pay down loyalty equal to a creature's mana value and it walks back out of the graveyard, gaining Vampire as a rider that matters only in the narrow builds that care about the type. That returned body sits inert unless it brought haste, so the minus is a value line, not a burst finisher. Working against that is the static: during your turn, every creature and every planeswalker you control drains, Sorin included, so the +2 gains a life each time it pings, and a plus-and-attack line refills the total the swing exposes. Ticking up while attacking commits you to aggression; the lifelink is what pays the cost of that commitment. The plus is unusual for a four-loyalty walker in that it hits only players or planeswalkers, never creatures, keeping Sorin out of trading with a blocker and pointed squarely at closing the game or grinding an opposing walker off the board. Everything routes toward one idea: a white-black midrange engine that gains life while it grinds, then converts a graveyard into a battlefield once loyalty is high enough to spend. The Vampire clause is flavor with the occasional bite. The lifelink clause is the load-bearing wall.
