Tenured Oilcaster
A self-fueling threat that clears its own bar. Most black threshold payoffs wait on your graveyard to fill; this one keys off the opponent's yard while pushing everyone's mill forward each combat, so the card that fills the eight-card requirement is often the creature itself, swing after swing. That makes the +3/+0 read less like a conditional bonus and more like a delayed inevitability: block it or race it, and the count still climbs. The 2/4 body invites a chump or a stall, but menace does the arithmetic, forcing two blockers onto what becomes a 5/4 attacker once the yard is stocked, and a defensive-looking creature converts into real pressure. The honest cost is symmetry. The attack-or-block trigger mills both players, handing opponents graveyard fuel that can feed their own recursion or delirium plans, so the card only wins the exchange in a deck built to profit less from a full graveyard than its opponents suffer from one: a beatdown shell aiming to close the game before the mill matters, not a grind deck that hands a mirror-image resource to the other side. As aggressive design it is unusually patient, a creature that grinds toward its own payoff rather than demanding you build a mill engine around it, and it asks the pilot to know exactly whose graveyard the game is really about.
