How to unlock WoW’s new Hearthstone Sarge mount
Blizzard released a new World of Warcraft mount for Sarge and it’s pretty easy to unlock the latest cross-promotion celebrating the Hearthstone Mercenaries update.
Players looking how to unlock Sarge in WoW will have to download Blizzard’s free-to-play online digital collectible card game. After that, the process gets much easier to complete to earn yourself a new mount.

WoW has a couple of Hearthstone-inspired mounts in the MMO already. Sarge’s Tale is the third piece of content from Blizzard’s other franchise in the shared universe.

Don’t forget, you’ll also need to start a new Bounty in the Mercenaries mode. If the mount doesn’t show up, then it could be delayed and Blizzard said it could take several hours to arrive.
