Blood-Cursed Knight

A 3/2 for is an honest floor by itself; the conditional upgrade is what the card is actually selling. Control any enchantment and the body grows to a 4/3 with lifelink, a jump on both axes at this cost. Everything hinges on how loose that "any enchantment" clause is: it doesn't ask you to enchant this creature specifically, doesn't care what the enchantment does, and counts only your own permanents. That makes the condition cheap to satisfy with anything from a one-mana aura to a sitting Banishing Light, but it also means the moment your board holds no enchantment you have a 3/2 with no abilities, so removal aimed at your enchantment strips the stat line and the lifegain in a single trade. The design reads as a payoff for a white-black enchantment shell, rewarding a deck already committed to that plan rather than asking you to bend toward one. The lifelink is the tell: it only matters while the bonus is live, which ties the card's racing math directly to whether your enchantment count holds. A 4/3 lifelinker swings a damage race hard; a naked 3/2 swings nothing. The whole package is a small lesson in conditional rates, where the printed body is the price of admission and the enchantment is the toll you pay to unlock the ceiling.
