Hearthstone: Battlegrounds

Battlegrounds is a game mode where eight players face off in 1v1 rounds, with the goal to be the last player standing. Each round consists of two phases. The Recruit Phase lets players purchase and sell minions, upgrade the tavern, use their hero power, and rearrange their minions' attack order. Combat Phase has minions automatically attacking the opponents' until one player (or both) has no minions remaining, at which point the victor attacks the loser.

Battlegrounds is significantly different from all other constructed play modes in Hearthstone, featuring completely different mechanics from anything previously seen. There is no mana: instead, the only resource is Coins (similar to the Bartender Bob, Bartendotron, and Bazaar Bob encounters from previous Single-player adventures). All minions cost 3 Coins, with the power of minions instead dictated by their Tavern Tier, shown in the usual place of mana on the card interface. This is a purple square on the upper-left with 1-6 (occasionally 7) gold stars. Minions do not attack the opponent directly - rather, surviving minions add Tavern Tier to the hero's attack once the round is over.
