Hearthpwn

The goal is to get the necessary cards as immediately as possible, as you want to win before he activates frostmourne. Letting him destroy those allowed me to draw what I needed without relying on other drawing techniques. 

Why wouyld you have ten spells when the first thing the Lich King does is destroy every spell in your hand and deck?

I would assume to thin through your deck, helping ensure you draw the cards you need to get to victory in 7 turns.
