Never in my life have I felt more alone than I did facing off against the final two bosses in Hearthstone: Curse of Naxxramas.
Mainly because, well, I was alone. Phil's on vacation, and his timing could not be worse. But there's also something about the nature of those final two bosses that instills a feeling of isolation within you. Like, for instance, boss number one, who only permits you to have two minions on the board at any given time. And then there's Kel'Thuzad, whose infinite supply of ice magic will freeze you until dead, like you're on some sort of solitary Antarctic expedition.
There's a lot of failure in the Overview video posted above — but there's a little bit of hope in there, too. And sometimes, a little bit of hope is all you need. Also, a well-timed Divine Spirit draw — you're going to need that also. Maybe twice.
