The gameplay of this deck is to mulligan for 1 mana damages, ram your spells and hero power to your opponent's face until you reach legend. The only way you can lose is if you don't draw well or if your opponent's solitaire deck draws better than you. Not many steps are needed to play this deck. Heck, even I can do it in 2 days.

Voracious Reader was too clunky from my experience. But if you're still unsure, you can change it with either of the two tradeables. Keep Rustrot Viper if you're seeing weapon-based decks or Impatient Shopkeep if you're seeing board-centric decks but it probably doesn't matter which one you take out since you're only going to trade them anyways.
