Always shuffle the spells. Shuffling big minions is a risk because you might draw a spell but it won't be the end all with this deck. You can keep Songstealer and Geist for Cubelock and Duskbreaker for aggressive decks.
The standard Spiteful Priest with Medivh as spell value insurance.
Many times have I drawn three of the only four spells in my deck early in the game. Once they are in your hand, they essentially lose all of their value for this deck. Unless you draw Medivh later on. This will allow you to use the spells while providing large threats against your opponent. It baffles me why he isn’t standard considering his win rate on metastats.net is hovering at 60%.
This deck has done wonders for me and is pretty much my signature standard ladder deck.
