Hearthstone: Madness Fair is an adventure addition to the board card game in the fantasy universe of Warcraft. Taking advantage of the holiday chaos, the ancient gods (C'Thun, N'Zoth, Yogg-Saron and Y'Shaarj) were able to return to the world of Hearthstone. Each of them has its own cry, which will strengthen a certain type of deck. In skillful hands, these cards can repeatedly help you get out of the most difficult situations and turn the course of the match in the right direction. It is worth noting that some cards will acquire a new “Corruption” property. Such cards will become stronger if they are in your hand and you play cards of higher value. Truly a crazy addition. Among other things, the game will feature a new “Duel” mode as an expansion of existing dungeons, and the system of achievements and tasks will be completely redesigned.
