It's not exactly a nerf, but it is a welcome change for most of the player base. Blizzard Entertainment aimed at the Discover mechanic that has been in the game since year one. The community sighed a breath of relief simultaneously. \n \nThe mechanic, as well as the produce another card minions and spells, generates a random card based, of course, from an internal RNG. No matter how small the percent is, these cards have always been able to discover themselves, which can cause an insane value-producing loop. \n \nhttps:\/\/twitter.com\/PlayHearthstone\/status\/1283084107401101320 \n \nThe most recent hotfix removes this capability. Hence the "Discover" cards and spells can no longer generate themselves. This response from the developers came after yet another meta criticism from Hearthstone players. After the release of its latest expansion, the Scholomance Academy, Paladins have, and Druids are the apparent winners of the current state. The top tier is followed closely by the various Priest and Mage decks. \n \nThese decks that copy cards from the player's opponents or generate random minion and spells are essentially 60 card decks, if not more. \n \nThe top iteration of Highlander Priest is sitting at 59% while the Galakrond Priest follows closely behind at 58.4%. In the case of Mage, it's more problematic for the developers than the class mentioned above. A Spell Mage version terrorize at 67% and Highlander Mage at 61.1%. \n \nThe developer notes state that the change will make "games feel a bit more varied." The post also adds that the mechanic can be thrilling for some games, "these types of experiences tend to have diminishing returns after a while." Finally, the statement concluded that this change would make for healthier games versus resource-based classes. \n \nhttps:\/\/twitter.com\/PlayHearthstone\/status\/1294028580683276288 \n \nAs a side note, cards like Priest's Shadow Visions can still make a copy of itself if the other is available in the player's deck. \n \nThere are also a few other hotfixes included. \n \n \tMr. Bigglesworth is now available in Battlegrounds to all players. \n \tFixed a bug where the selected minion summoned by Jandice Barov would not have the death upon damage enchantment when summoned again with Khadgar. \n \tFixed a bug where Headmaster Kel' Thuzad would not resurrect minions that were destroyed from being returned to a full hand. \n \nBecause these adjustments are happening on the server-side of the game, there is no need for downloading a new patch if the game client already has the 18.0 version of Hearthstone. \n \nWhile on the foreground, this looks like a nerf to the Priests and Mages, some players are pointing out that this buffs the classes. Since the same card generator cannot be found anymore, the cards have a chance to discover even better cards for the state of the board.
