Horrors you control have menace.
Whenever a Horror you control deals combat damage to a player, that player mills that many cards.
At the beginning of your end step, choose target artifact or creature card in an opponent's graveyard that was put there from their library this turn. Put it onto the battlefield under your control.
Assemble a board of Horrors with built-in menace, swing to mill opponents for big chunks, then steal the best artifacts and creatures their library dumps into the graveyard during your end step. You grind value off opponents' decks while building a snowballing board, eventually winning through evasive combat damage or sheer accumulated theft.
Add changelings and Horror-makers (Maskwood Nexus, Realmwalker, Universal Automaton, Mistform Ultimus) to deepen the tribe and ensure every body carries menace. Lean into mill-payoff and evasion enablers plus cheap interaction to protect N'ghathrod, and consider self-mill-into-reanimation backups so you aren't fully dependent on opponents having juicy targets. Tighten the mana base with Dimir duals, fast mana like Fellwar Stone and Arcane Signet, and tutors such as Vampiric Tutor to find your engine pieces reliably.
