Night's Whisper

Two mana for two cards is respectable, but sorcery speed and life loss are a poor rate beside Modern's cheaper selection and proactive threats.

Could be wrong if A black attrition shell that values pure card quantity over velocity could make it a fringe inclusion.

Night's Whisper is far slower than Ponder and Brainstorm-style selection and does not support Legacy's strongest mana or graveyard engines.

Could be wrong if A future black control shell lacking blue cantrips could want a modest amount of reliable card advantage.

A clean two-mana two-for-one is meaningful at common and can support slower black decks, though paying life and taking turn two off constrain it.

Could be wrong if Pauper's fastest decks and stronger synergy-based draw engines may leave little room for a generic sorcery-speed draw spell.

One mana plus black for two cards is efficient, and two life is trivial at 40; it is solid generic draw but lacks multiplayer scaling or synergy.

Could be wrong if Optimized lists may favor repeatable engines, tutors, or synergistic draw over a replaceable one-shot effect.

Two mana to draw two is reliable card advantage and the life loss is usually manageable, though casting it early can concede battlefield tempo.

Could be wrong if Unknown set speed, removal, and black's card-draw density could make spending turn two off-board substantially worse.
