Zodiark, Umbral God

Five black pips, no fixing, no colorless anywhere in the cost: the mana line does nothing but confirm you built a dedicated mono-black shell before this ever reached the table. What it buys is a board wipe that leaves your own threat standing. The entry trigger is symmetric edict math (each player culls half their non-God creatures, rounded down), but the wording routes every one of those deaths back into the same body: any creature sacrifice, including the ones its own arrival forces, grows it. That is the pivot the design turns on. Most mass-sacrifice effects punish the caster as hard as the opponent; this one launders the shared cost into a one-sided payoff, because the indestructible God is exempt from the edict it just fired and then feeds on the wreckage. Rounding down is the throttle: small boards survive intact, so the card asks to be cast into a developed table rather than an empty one. And because it reads any creature sacrifice, not just the entry trigger, every aristocrats outlet and edict already in the deck becomes fuel for the counters. The accrual is permanent, and indestructibility forces removal to answer it sideways: exile, bounce, a forced sacrifice, or racing wider than it can eat. A finisher that fattens on the carnage it authored, priced so that only black ever pays the bill.
