Deck Name: Millborn Horrors
-----------------------------------------------------------------------------------------------
Format: Casual Multiplayer
Deck Type: Mill / Graveyard Control
Colors: Blue-Black (Dimir)
-----------------------------------------------------------------------------------------------
Description

"Millborn Horrors" is a multiplayer Mill & Graveyard Control deck that systematically erodes opponents' libraries, leaving them defenseless and without options. By leveraging Phenax, God of Deception, Bruvac the Grandiloquent, and powerful mill spells like Mind Grind and Fractured Sanity, this deck forces opponents into an inevitable loss.

The deck also controls graveyards through Leyline of the Void, Planar Void, and Dauthi Voidwalker, ensuring that milled cards cannot return to haunt you. Support spells like Mana Drain, Damnation, and Cyclonic Rift protect you from threats, while Undead Alchemist converts milled creatures into a zombie horde for additional pressure.

"Millborn Horrors" thrives in multiplayer games, where its mill strategy impacts multiple opponents at once. The longer the game progresses, the deeper your opponents sink into the abyss, until their libraries are no more.

How to Play

Early Game:
Establish mana acceleration with Skyclave Relic, Midnight Clock, and Solemn Simulacrum.
Use Fractured Sanity, Maddening Cacophony, and Psychic Corrosion for early-game mill pressure.
Keep counterspells like Mana Drain and Negate ready to stop early threats.

Mid-Game:
Deploy Phenax, God of Deception and Consuming Aberration to amplify mill output.
Use Dauthi Voidwalker, Planar Void, and Leyline of the Void to shut down graveyard-based decks.
Wipe the board with Damnation or Extinction Event if the battlefield gets out of control.

Late Game:
Use Mind Grind or Drown in Dreams to eliminate opponents' libraries in one massive strike.
If Bruvac the Grandiloquent is on the battlefield, a Traumatize or Archive Trap can remove an entire deck instantly.
Leverage Breach the Multiverse to steal and use key opponent cards against them.

Once an opponent’s deck is fully milled, they lose as soon as they attempt to draw a card.

How the Mill Strategy Works

Small, Continuous Mill Effects:
Psychic Corrosion, Riddlekeeper, Ruin Crab mill opponents consistently, weakening their decks over time.

Explosive Mill Spikes:
Phenax, Mind Grind, Fractured Sanity unleash massive mill bursts, often removing 10+ cards per player in one move.

Mill + Graveyard Lockdown:
Leyline of the Void, Planar Void, and Dauthi Voidwalker ensure milled cards never return.

Mill as a Win Condition:
With Bruvac the Grandiloquent, any mill spell becomes twice as effective, making an empty library inevitable.
