Mark of the Vampire
The trouble with attaching this much value to a single creature is that the creature becomes a magnet for removal: spend four mana to turn one body into a +2/+2 lifelinking threat, and a single kill spell answers both halves at a two-for-one. That math has kept simple stat-and-keyword Auras like this one out of competitive play for most of the game's history, where Equipment that survives the death of its bearer wins the trade-off war. What the Aura buys instead is a body that is genuinely larger now: lifelink turns every swing into a swing in your life total, and on an evasive or already-sizable creature, the gap between racing and being raced closes fast. The design sits in the comfortable middle of black's toolbox, a curve-filler for decks that care about attacking and gaining life in the same motion rather than building a combo around it. The intended audience is a player learning that a creature you cannot block is worth more than its printed stats, and that gaining four life on a connecting attacker can flip a damage race that looked lost. Nothing here is doing structural work; it is honest, on-the-nose black flavor at a rate that asks you to be ahead before you cast it.
