Deathknell Berserker

A 2/2 that dies for nothing left to its own devices, and pays out only when something has hoisted its power to 3 or higher by the moment it hits the graveyard. That conditional is the entire deckbuilding proposition: unbuffed, the trade is even and the death trigger whiffs; buffed, the same creature leaves a 2/2 black Zombie Berserker behind and effectively replaces itself. The check reads power at the instant of death rather than at any earlier point, so any source works, whether a standing anthem, an aura, a +1/+1 counter, or an instant-speed combat trick cast in response to removal. A static buff that was already live counts exactly as much as one played on the spot. The reward is tuned to black's aristocrat instincts: a body that spawns another body when it trades or gets sacrificed feeds sacrifice outlets and death payoffs twice from one investment, which is where the small clause earns its keep. Black has printed plenty of two-drops that hand you a conditional instead of value up front, and this one closes the gap between its floor (a beatstick that dies for nothing) and its ceiling (a self-replacing threat keeping a go-wide engine fed) with the smallest possible nudge to its power. Clearing that three-power bar at the right moment is the cost of admission.
