Quote From Blizzard

Patch 27.4 brings the Fall of Ulduar Mini-Set; Yogg-Saron has escaped and is spreading his Anomalies across Hearthstone!

 

Ulduar Has Fallen

The titans left their charges to watch over the imprisoned Yogg-Saron, but no prison lasts forever. The Old God has escaped to once again wreak havoc on Azeroth! Will you fight back, or will you succumb to the madness within?!

There’s a new Titan in town. Cast spells to fuel the Old God’s power, bring madness to the Tavern with Chaotic Tendrils, and unleash Yogg-Saron on your opponents with this Mini-Set of 38 all-new cards. Get them in TITANS packs, or as a complete 72-card* Mini-Set. Get the normal version in-game for $14.99 or 2000 Gold, or get the all-Golden version for $69.99 or 10,000 Gold. The all-Golden version also comes with a bonus Diamond copy of the Yogg-Saron, Unleashed Legendary minion! You can see all the cards from the Fall of Ulduar Mini-Set in the official Card Library.

* 4 Legendary cards, 1 Epic card (2x), 17 Rare cards (x2), and 16 Common cards (x2).

 

Yogg-Saron's Anomalies Consume Hearthstone!

It’s all so clear now: Yogg-Saron's whispers have been corrupting Battlegrounds this entire Season. Now, Yogg-Saron has escaped, and Anomalies are appearing in Standard, Wild, Twist, Casual, Arena, and Practice Modes, too! The following Anomalies have been unleashed upon the Tavern:

 

 

 

Twist Reality After a player plays a card this game, shuffle a copy into their deck.
Approaching Nightmare Both players start with Yogg-Saron, Hope’s End in their hand.
Opportunity Knocks The first card drawn on a player’s turn is one they can afford to play.
Shifting Fate Both players start with Gear Shift in their hand.
Light in the Dark Both players’ Hero Powers cost (1) less.
Gift of Gluttony Both players start with two more drawn cards.
Shifting Futures Both players start with 2 copies of Shifter Zerus in their hand.
Control the Makers Both heroes have +1 Attack on their turns.
Severed Souls Both heroes start with +5 Health.
Surging Inspiration Both heroes start with upgraded Hero Powers.
Driven to Greed Whenever a player ends their turn with unspent Mana, they get a Coin.
Driven to Excess Whenever a player ends their turn with unspent Mana, they draw a card.
Uncontrollable Growth Both players start with an extra Mana Crystal.
Seeing Double Both players start with 2 cards copied from the other players’ hand.
Unimaginable Horrors Both players Discover a new basic Hero Power on their first turn.

Your Eyes Betray You Both players’ cards are Golden.
Army of the Corrupted The first minion played on each player’s turns costs (1) less.
Spread of Corruption The first spell played on each player’s turns costs (1) less.
 

For one week following the launch of Patch 27.4, Anomalies will appear in 100% of Standard, Wild, Twist, Casual, Arena, and Practice Mode games. After that one-week period, they will appear in 25% of games until Patch 28.0. Cho’gall, Twilight Chieftain’s effect offers an additional chance for an Anomaly, meaning that you could have up to two Anomalies active in a game during this event period if you and/or your opponent have Cho’gall in your deck(s). In games where Anomalies are present, all Anomalies have an equal chance of appearing.

Battlegrounds Updates

Damage Cap Update

The damage cap now persists for all players until the Top 4. The primary goal of the damage cap in Battlegrounds is to protect players from taking too much damage too early. We’ve heard a lot of feedback from the community that the system was not fully achieving that goal, so now we’re expanding it even further. We’ll closely monitor this change and make additional changes to the damage system as needed.

 

New Anomalies

The following Anomalies will be added to Battlegrounds throughout Patch 27.4:

 

 

 

The Yogg-iseum At the start of each turn, spin the Wheel of Yogg-Saron.
Dev Comment: Each turn, the Wheel is spun and one result is chosen for all players.
Blessed or Blighted? Start of Combat: Give your left-most minion Divine Shield and your right-most minion Reborn.
Golganneth’s Tempest Minions cost 2 Gold. You cannot Refresh the Tavern. It Refreshes itself after you buy a minion.
Match Fixing Guess which player will win your next combat. If you're correct, get 3 Gold Coins.
Up-Prizing After you upgrade the Tavern, Discover a Tier 1 Darkmoon Prize. (Improves in 3 turns!)
Gladiator’s Spoils After you win a combat, Discover a minion of your Tier. Otherwise, get a random one of a Tier lower.
Shackles of the Primus After each combat, remove your warband. At the start of your turn, triple your Gold.
Summoning of Champions At the start of the game, all players Discover a Tier 6 minion from the same choices.
Curse of Aggramar Start at 5 Health and 5 Gold. Your hero can only take 1 damage at a time.
Reckless Enhancement Minions in the Tavern each randomly gain Taunt, Windfury, Divine Shield, or Reborn.
Tavern Special All minion types are in the Tavern. It always has 7 minions.
Eonar’s Overgrown Arena At the start of your turn, give minions in the Tavern +1/+1 for the rest of the game.
