Wield Ancient Power

Reign of the Black Empire features the four Old Gods as Legendary Neutral minions:

• C’Thun, Eye of the Empire rewards unwavering devotion and the fulfillment of its dark designs.
• N’Zoth, Dream’s End spreads corruption through patient planning and inevitable decay.
• Mastermind Yogg-Saron seizes control, unleashing chaos through those who serve it.
• Y’Shaarj, Titan Bane overwhelms its enemies through sheer size, strength, and domination.

This is the age of the Black Empire, when these nightmarish rulers stood at the height of their power and their influence shaped all of Azeroth. Their strength is so immense that you may include only one Old God in your deck. Each Old God possesses four potent once-per-game abilities and, instead of attacking, can invoke two of those powers each turn. Once all four abilities have been exhausted, the Old God is free to attack and join the battle directly.

C’Thun, Eye of the Empire

C’Thun rewards those who dedicate themselves fully to its cause. Trigger all four of C’Thun’s abilities with cards like Spawn of C’Thun to prove your devotion, then summon C’Thun, Eye of the Empire and unleash powers beyond mortal comprehension, tripling the effects of every one of its abilities. What begins as a formidable threat becomes a devastating embodiment of the Black Empire’s might.

Mastermind Yogg-Saron

No one truly controls Yogg-Saron, the God of Nightmares. Play Mastermind Yogg-Saron, surrender control, and watch as it takes an entire extra turn on your behalf. Whatever happens next is in Yogg-Saron’s hands now.

N’Zoth, Dream’s End

N’Zoth is the master of corruption, quietly extending its reach until resistance becomes impossible. Build your army, manipulate your Deathrattle effects, and unleash devastating payoffs worthy of the master of corruption. Surrender to the whispers and discover how far N’Zoth’s corruption can spread.

Y’Shaarj, Titan Bane

Y’Shaarj rewards decks built around enormous minions and overwhelming threats. Survive the early game and this seven-headed horror will help you dominate the battlefield through sheer force.

New Keyword: Assemble

As the Old Gods and Titan-forged build their armies for war, you’ll do the same with Assemble. Add a minion to your hand, then replace part of its card text with the text of another minion from a curated pool. Assemble creates unique combinations and lets you tailor your forces to fit your strategy.

The Titans Strike Back

Long before heroes walked Azeroth, the world was shaped by a war between cosmic powers. When the Titan Pantheon discovered Azeroth being corrupted by the Old Gods, they responded by creating an army of Titan-forged servants powerful enough to fight back. In Reign of the Black Empire, you’ll experience that legendary conflict from both sides. Command ancient Old Gods and wield their unfathomable powers, or fight alongside Azeroth’s greatest defenders as legendary Titan Watchers and celestial magic enter the battle. The fate of the world is in your hands.

Isiset Awakens

Among the Titan-forged champions who rose to oppose the Black Empire, few wielded power as devastating as Isiset. This Legendary Titan Watcher brings enormous late-game potential to Mage decks. Her Battlecry summons two massive 10/10 Constructs that remain Frozen until you’ve spent 15 Mana on spells. If you can unlock their power, your opponent will suddenly be staring down 20/20 worth of Titan-forged Constructs.

Arrival of the Old Gods

The corruption begins. Arrival of the Old Gods draws minions, refreshes Mana Crystals, and enables explosive creature-focused turns worthy of Azeroth’s ancient rulers.

Arrival of the Titans

The Titans answer. Arrival of the Titans draws spells, refreshes Mana Crystals, and lets spellcasters unleash devastating combos ahead of schedule.

Dark Terraforming

The Black Empire reshaped Azeroth through corruption and violence. Dark Terraforming spreads damage across the battlefield, showcasing the destructive influence of the Old Gods.
