Greed

The original repeatable black draw engine, and the template Wizards has been rebalancing ever since. The design is uncompromising on purpose: no tap, no once-per-turn clause, no upper limit on activations. The only governors are mana, which you have plenty of by the time it lands, and life, which black is already structured to spend. Every successor inherits something from this skeleton, and most pay for the privilege by adding friction this card refuses: Phyrexian Arena ratchets the tempo down to one card a turn at a fixed life cost; Dark Confidant moves the variance onto whatever card is revealed; Underworld Connections taxes a land. Necropotence went the other direction entirely, trading the whole draw step for an end-step refill at one life per card and no mana at all, a far higher throughput than this card's two-life-and-a-black ever reaches. So the lesson here is not that nothing surpassed it; plenty did. The lesson is in the friction points this card lacks. Modern black card-draw almost always taxes one additional axis (a creature in play, a sacrifice, a life threshold, a turn limit) because the unbounded version, printed before the color pie understood what black draw was supposed to cost, set a ceiling the rest of the cycle has been negotiating around: either by capping the rate, as Arena does, or by removing the cap and paying for it in life and structure, as Necropotence does.
