I don’t like light bomb, for its situationality and the six manna cost. Instead I would rather to bring 2 5 Holy Nova 2 for its synergies with Injured Blademaster Holy Champion and Vol'jin .
Holy Champion if invocated in the right turn, especially with deathlord in the field could be a definitive strike to your opponent.
Thoughtsteal and Museum Curator are important in order to not running out of cards.. Museum Curator has become one of the best discover cards, with the high odd to pick a legendary card such as a second Sylvanas Windrunner or Sneed’s Old Shredder.
In this type of control deck I don’t were cabal shadow priest due to the lack of space for the synergies with Shrinkmeister. When would suit much better in a mental control deck which would have sinnergies with other cards such Shadow Madness or Shadow Word: Pain. However if you don’t have of the legendary cards one of the legendary cards on this deck, Cabal Shadow Priest could be a good replacement.
Velen's Chosen goes well due to the wide range of low value minion.
Auchenai Soulpriest is essensial card for it’s sinergies with Circle of Healing , Flash Heal and Justicar Trueheart .
