30 Unstable Portal Fun: Hearthstone Blackrock Class Challenge
After the 30 web spinners in the first hearthstone expansion that was naxx, blackrock brings out the 30 unstable portal madness!
It’s a rather crazy random summon of magical proportions! You get to play all the legendaries you won’t have to pay a single cent for, though the 700 gold for the stage might take you a week to farm if you are going free to play.
Having it on mobile really makes it more convenient to go for a round or too, especially since games are saved during AI to be resumed.
