Madness at the Darkmoon Faire is Hearthstone's sixteenth expansion, featuring 135 new collectible cards. The expansion was released on November 17th, 2020. This expansion takes place on the mysterious Darkmoon Island, on the fairgrounds run by Silas Darkmoon and his carnies... with four sinister guests from the depths of the Void. This expansion adds the new Corrupt keyword, which powers up corruptible cards in your hand by playing a card that's more expensive than it. It also features the return of the Old Gods Yogg-Saron, C'Thun, Y'Shaarj and N'Zoth (the latter of which is also now a new Hero).
