If you've played Blizzard's digital card game Hearthstone: Heroes of Warcraft then you are intimately aware of the spinner that runs before every ranked/unranked match, the rotating dial eventually selecting your "Worthy Opponent" before the match start. But there are many other potential heroes upon that list. "Who are they?", you've probably wondered? Diligintely (and exhaustively), we've answered that question so you don't have to.
