With Hearthstone's Year of the Raven kicking off with the launch of the upcoming Witchwood expansion on April 12, fans of Blizzard's wildly popular card battle game are about to experience some of the most sizable changes to the game yet. Compared to the previous expansion, Kobolds and Catacombs--which introduced the Dungeon Run--The Witchwood expansion brings in a slightly spookier experience for its jaunt through the dark and dreary forest. Along with 135 brand new cards, new keywords known as Echo and Rush, special hero characters that can transform into Worgen (Warcraft's take on werewolves), and a new variation to the Dungeon Run called Monster Hunts--the thriller-themed expansion aims to switch up the meta of the game.

During PAX East 2018, we spent some time with Hearthstone's game director Ben Brode, where he showed off new cards and spoke about the big changes happening in the coming weeks. In addition to talking about the Witchwood expansion, he also reflected on the game's impact, how its expanding community keeps the studio on their toes, and why the new content and flow will make it great entry point for new players.
