Clash Royale is unleashing Viking Season, bringing two new Heroes and a new Evolution into the mix.

What we love: The Heroes bring a fresh twist to some classic Troops. The Hero Valkyrie, who can be obtained in the season pass, changes from a defensive unit into a destructive force. And the Hero Berserker, who you can unlock in a special event challenge, launches into a furious frenzy, with a temporary moment of invincibility.
