Druid combos will be a little less powerful in Hearthstone pretty soon, as Blizzard prepares to nerf a number of classic cards alongside the newest expansion. Newly nerfed classic cards include some core favourites like Ironbeak Owl, Leper Gnome and Knife Juggler. Powerful Druid cards like Keeper of the Grove and Force of Nature will also be weaker after the patch. (Full list of changes below.)
The next Hearthstone expansion, Whispers of the Old Gods, will go live on April 26. It will make some big changes to the way multiplayer games are played.
Here are all the nerfs, displayed in helpful image form via Battle.net. I've also included Blizzard's explanation for each one.
Ancient of Lore
Drawing cards is powerful in Hearthstone, and Ancient of Lore easily found its way into nearly every popular Druid deck. We'd like Druid players to feel that other cards can compete with Ancient of Lore, so we've reduced the number of cards drawn from 2 to 1.
Force of Nature
The new version of Force of Nature lowers its mana cost by 1, but removes Charge and makes the summoned Treants permanent -- like the other Treants that Druids summon. This change also removes the powerful one-turn combo of Force of Nature and Savage Roar. Now, opponents will have a chance to deal with the threat that the Treants represent, and it won't feel mandatory to always include the combo.
Keeper of the Grove
Keeper of the Grove is a strong and versatile minion that combines Silence with solid stats, which made the decision to include it in every Druid deck virtually automatic. Whether or not to introduce a source of Silence to a deck should require some decision making, so Keeper of the Grove shouldn't be a default choice for all Druid decks. Its stats have been changed from 2/4 to 2/2.
Speaking of Keeper of the Grove, Silence and minion removal are potent effects in Hearthstone. Currently, some removal options are too widely played, are attached to minions with efficient stats, or are simply too powerful. While removal is an important part of Hearthstone, it also makes playing big, exciting minions less rewarding. We are adjusting some of these cards so that the decision to add them to your deck comes with a cost, especially if you don't end up finding an ideal target for them. These changes should help make cards with high attack or cool effects more interesting too.
Ironbeak Owl is a staple source for an inexpensive Silence in many decks. In line with our overall goal to make Silence effects more costly, Ironbeak Owl is moving from 2 to 3 mana.
Big Game Hunter
Big Game Hunter represents an inexpensive source of removal that is packaged with a minion. It's efficient enough that some Heroes with powerful Class-based removal cards choose to run the neutral Big Game Hunter. We're increasing the cost of the card from 3 mana to 5 mana.
Hunter's Mark is an important option for Hunters, but it's too efficient at 0 mana. We are increasing its cost to 1.
Blade Flurry is a problem because it enables both board clear and heavy burst damage, and it's also an obstacle to adding better cards for Rogues. To address these issues, the cost of Blade Flurry is moving from 2 to 4 mana, and it will now only affect minions, so that Rogues have to choose between removing threats or damaging the enemy Hero.
Knife Juggler should be a good choice in decks that play many cheap minions, but with 3 Attack, it is played almost universally. We're reducing Knife Juggler's Attack from 3 to 2, so this card will move into a more specialised role in the decks that include it, instead of always being among the best choices for a 2 mana-cost minion.
Leper Gnome is powerful for its cost, finds its way into almost every aggressive deck, and requires no further deck building decisions to be effective. We'd like other 1 mana minions to be more compelling, so we're reducing its Attack from 2 to 1.
Charge is an ability we've learned to use sparingly. Arcane Golem has been a staple in many aggressive and 'one turn kill' combo decks, and its drawback is rarely relevant. We're addressing both issues by removing Charge and increasing Arcane Golem's Health, while leaving its drawback. Arcane Golem will now be a 3 mana 4/4 with Battlecry: Give your opponent a Mana Crystal.
Molten Giant is an interesting card, but it's too easy for players to reduce its mana cost to 0. We're increasing Molten Giant's mana cost to 25 to increase the risks players must take to get a free Giant. The changes to Force of Nature and Arcane Golem will make dropping to low health somewhat less risky as well, which helped spur this change.
Master of Disguise
The ability of Master of Disguise to grant permanent Stealth has been a design obstacle for a long time, so we are changing Master of Disguise to only grant Stealth until the next turn. This change opens up exciting options for future cards.
