Updated for Lorwyn! More powerful then ever! Double Demon Combo!

This new mono-black Demon combo deck is built to end games the moment the pieces come together. Bloodletter of Aclazotz turns every life-loss effect into a lethal threat, and when paired with Unstoppable Slasher, opponents quickly realize their life total is no longer safe.

Rush of Dread is the finisher that pushes the deck over the edge. With Bloodletter on the battlefield, a single Rush of Dread can immediately strip massive chunks of life, often ending the game on the spot. Unholy Annex fuels the engine, while Demon Wall, Firdoch Core, and Soulstone Sanctuary keep the deck stable long enough to assemble the combo.

This deck excels at punishing tapped-out opponents and slow setups. It doesn’t rely on combat, ignores board stalls, and forces instant concessions when the combo resolves. If you enjoy mono-black decks that win out of nowhere and leave opponents staring at the screen in disbelief, this Demon combo is for you.
