Vampirism

A self-cannibalizing power play, and a strange one: the Aura turns your whole board into fuel for a single creature, shrinking every other body by 1/1 while the enchanted one swells to match the count it just thinned. The math is deliberately self-correcting. The more creatures you have, the bigger the bonus, but the -1/-1 to everything else means you are trading width for one enormous threat and often killing your own smallest tokens in the process. That is the cost the design builds in to keep the swing from being free. The card draw is a small concession, timed to the next upkeep rather than immediately, so you bank a card but cannot turn it into a same-turn reaction. What makes the effect sit oddly in black's toolkit is that it weaponizes your own creatures as a power source without a sacrifice trigger: the shrink is an anthem run in reverse, but pointed only at your side, which means the carrier feeds entirely off your own board and never touches the opponent's. It rewards a board built around a single carrier rather than a swarm, an unusual ask for an Aura that scales off creature count. The result is a card that wants two contradictory things at once: it counts your creatures to size the bonus while actively diminishing them, and the tension between those two clauses is the whole design.
