Blizzard has big plans for Hearthstone in 2021. The Year of the Gryphon will introduce three new expansions, each with its own mini-expansion, formulating a year-long narrative starring an all-new cast of characters. The underlying structure of the game will undergo a massive shift too, with the introduction of the Core set and new spell schools. And sometime later this year, a new Mercenaries mode will turn the familiar card game into a roguelike RPG.

Fresh off the presentation at BlizzConline, we spoke with senior game designer Alec Dawson and associate game designer Cora Georgiou about the plans for the coming year and lessons learned from past expansions.
