Hearthstone: Rise of the Mech event adds a free Legendary, buffs 18 cards, and ushers in Arena rotation

Blizzard Entertainment isn’t taking you to the beach this summer — instead, you’re going to the hot, sweaty, and loud secret lab of Dr. Boom. Get ready for Rise of the Mech, a Hearthstone: Rise of Shadows event that begins June 3 and ends July 1 that gives players a new Legendary Mech, permanently improves (or “buffs”) two cards from each class (18 in total), and ushers in the first two-month rotation in the Arena.

Hearthstone rules the roost in a digital card game market that research firm Newzoo estimates could be worth $2 billion by 2020, and events such as Rise of the Mech help engage players who may be feeling tired of the metagame or bring back others who have lost interest or drifted off to other games. The news also comes a day after Blizzard announced a round of nerfs that target some of the most oppressive decks in the metagame.
