Mulligans
Aggro Mulligans
Typically for an anticipated aggro matchup, you want to look for Northshire. He is just good and with your power he can become very effective. As you progress, Shadow madness wil also be helpful. AoE combo is also a good keep. Don't forget Power Word!
Control Mulligans
Museum Curator cant be anymore effective. Also try to play starseeker asap! Otherwise this deck is geared for control.
If you like control decks and priest is in your blood, then say hello to this wonderful and fun control deck! This deck is a typical control with a twist:Elise Starseeker! Many games where opponents had no answers to golden monkey. It runs AoE combos like Soulpriest/Circle, etc. Fun and Effective thats what I like to introduce to you guys.
