The 23.0.3 patch brings balance changes to three Hearthstone Game Modes. Learn about all the nerfs in this article.

Hearthstone released today the Patch notes for the update 23.0.3, including the nerfs that we anticipated last Thursday. On top of that, Battlegrounds and Duels are also getting balance changes. Join us in this recap of Hearthstone Patch 23.0.3.

Hearthstone Patch 23.0.3: Constructed changes

Last Thursday Gallon anticipated the nerfs we would be getting today. Nevertheless, let’s go over the changes that come with the 23.0.3 Hearthstone Patch.

Hearthstone Patch 23.0.3 Kazakusan nerf
Old: Battlecry: If all minions in your deck are Dragons, craft a custom deck of treasures.  New: Battlecry: If you played 4 other Dragons this game, craft a custom deck of treasures.
Hearthstone Patch 23.0.3 Miracle Growth
Miracle Growth
Old: [Costs 7]  New: [Costs 8]
Hearthstone Patch 23.0.3 Secure the Supplies
Secure the Supplies (the third portion of the Warrior Questline, Raid the Docks)
Old: Play 2 Pirates.  New: Play 3 Pirates.
Hearthstone Patch 23.0.3 Pufferfist
Old: 3 Attack, 4 Health  New: 3 Attack, 3 Health
Hearthstone Patch 23.0.3 Switcheroo
Old: Draw 2 minions. Swap their stats.  New: Draw 2 minions. Swap their Health.
(Banned in Wild)
Hearthstone Patch 23.0.3 Kael’thas Sunstrider
Kael’thas Sunstrider
Old: Every third spell you cast each turn costs (0).  New: Every third spell you cast each turn costs (1).

The changes in the 23.0.3 patch aim to balance Hearthstone’s metagame. This is the first balance patch we get after Voyage to the Sunken City expansion launched. Druid’s power level was out of the charts, and the deck’s popularity consequently rose to the roof, creating an unhealthy player experience.

Many players were surprised by the lack of nerfs to Demon Hunter. Gallon mentioned that they will “be keeping a close eye on the post-patch metagame to see how aggressive Demon Hunter list fare once slower decks are given a better chance.” This makes sense since control was pushed out of the metagame by Kazakusan Druid.

Remember that the cards affected by Hearthstone Patch 23.0.3, except for the uncraftable Kael’thas Sunstrider, will be eligible for full dust refunds until May 12.

Hearthstone Battlegrounds 23.0.3 Patch notes

Hearthstone Battlegrounds also received some changes with the 23.0.3 patch. The main target of this patch was to tone down Murloc’s power level.

Hearthstone Patch 23.0.3 Ini Nerf
MechGyver (Ini Stormcoil’s Hero Power)
Old: Passive: After 9 friendly minions die, get a random Mech.  New: Passive: After 12 friendly minions die, get a random Mech.
Aquarrior (Varden Dawngrasp’s Buddy)
Aquarrior (Varden Dawngrasp’s Buddy)
Old: [Tavern Tier 2] 3 Attack, 5 Health.  New: [Tavern Tier 3] 3 Attack, 6 Health.
Hearthstone Patch 23.0.3 Sefin Nerf
Old: Avenge (3): Give a friendly Murloc Poisonous permanently.  New: Avenge (4): Give a friendly Murloc Poisonous permanently.
Hearthstone Patch 23.0.3 Murloc Nerf
Coldlight Seer
Old: [Tavern Tier 3]  New: [Tavern Tier 4]
Baby Krush
Baby Krush
Old: 7 Attack, 7 Health. Whenever this attacks, summon a 9/9 Devilsaur to attack the target first.  New: 6 Attack, 6 Health. Whenever this attacks, summon an 8/8 Devilsaur to attack the target first.

The 23.0.3 Hearthstone patch hit Murlocs hard with the nerf to SI: Sefin and Coldligh Seer. Murloc compositions were sometimes too good to beat, and Sefin itself was a powerful minion. On top of that, Ini Stormcoil received a huge nerf, the second in her short lifespan, that will probably send her down the tier list and maybe make her unplayable.

Duels Changes

On top of the Constructed and Battlegrounds changes, Duels is getting some fine-tuning with Hearthstone patch 23.0.3. What stands out in these changes is the Dev Comment on Humble Blessings, which reads “My bad”. We forgive you and love your sense of humor, Ates “Tabayrak” Bayrak! Maybe it was Brad who made you do that.
