Hearthstone nerfs Giggling Inventor, Mana Wyrm, and Wild’s bane — Aviana

Blizzard Entertainment announced nerfs for three Hearthstone cards today. The changes to the PC and mobile digital card game will go live on October 15, and they will impact the Neutral minion Giggling Inventor, the Mage minion Mana Wyrm, and the Druid Legendary minion Aviana.

Hearthstone is the king of the digital card game market, with intelligence group SuperData estimating the free-to-play game will bring in $414 million in revenue this year. Hearthstone makes most of its money by selling digital card packs to players. To keep fans buying packs, they have to keep playing the game. These balances changes can keep fans satisfy while creating a more fair competitive environment, which can help Hearthstone stay on top of the digital card game genre against rivals like Gwent (and Valve’s upcoming Artifact).
