'It's about time!': Hearthstone is getting a Starcraft crossover set starring Raynor, Kerrigan and Artanis
It's pretty wild that over its decade-long life, Hearthstone hasn't done any major crossovers with other Blizzard games. Obviously it's based on the Warcraft universe, but given the liberties taken with that source material (the current expansion involves launching spaceships) it's a surprise that we haven't seen any significant team-ups. That changes next January, with the launch of the Heroes of Starcraft mini-set.
