Gloom Sower

Blocking this thing is a punishment, not a wall. An 8/6 body at seven mana is already awkward to trade with, but the drain trigger flips the usual math of chump-blocking: every creature thrown in front to buy a turn hands over two life and refunds it to the attacker. Against a mono-black beater the defender's own defensive plan becomes a life-total swing, so the choice narrows to taking eight or bleeding two-at-a-time while doing so. The design leans on a familiar bit of black creature philosophy (make my creature actively hostile to interact with, the way menace, deathtouch, or a Nighthawk-style lifelink body taxes the block) but routes it through pure life economy rather than combat keywords. Note the trigger fires once per blocker, so a gang-block that would normally kill it also multiplies the drain, which quietly discourages the exact response big fatties usually fear. The result is a top-end body built for racing: hard to block profitably, and steadily correcting your own life total upward every time an opponent tries to stand in its way.
