Welcome to Duels, a new competitive Hearthstone game mode that changes every season! In Duels, you’ll choose a Hero, a Hero Power, a starting Treasure, and build a 15-card starter deck from your collection before facing off against a series of worthy human opponents—Dungeon Run-style! Devise your path to victory by enhancing your deck after each match with minions, spells, and powerful Treasures to aid in increasingly difficult encounters with other players!
