Cards equivalent to “Growing Dread” (an enchantment from Murders at Karlov Manor that transforms into “Dread Presence” after conditions are met), in black, would be cards with repeatable payoff for creatures dying or for investigating/Clue synergies. Examples:
1. “Open the Graves” – Creates tokens when your nontoken creatures die.
2. “Grim Haruspex” – Draws a card when your nontoken creatures die.
3. “Deathreap Ritual” – Draws cards when creatures die each turn.

Reason: These cards similarly reward you for creatures dying, a key part of “Growing Dread.”
