Silence Priest

Thanks to two silence card additions from Rise of Shadows, Dalaran Librarian, Unsleeping Soul and multiple new cards working great with friendly minion silence effect Arcane Watcher, Hench-Clan Shadequill, Soldier of Fortune along with old ones Ancient Watcher, Quartz Elemental makes the basis for a great tempo deck with a strong presence on the board.

Card draw is assured by classic combo Northshire Cleric  + Wild Pyromancer.

Board clear in case of drawing unfavourably can be done with combination of:
Auchenai Soulpriest  + Circle of Healing
Wild Pyromancer + Power Word: Shield 

I am personally really eager to try this one and believe this could be a competitive deck that is invulnerable to silence and combo-breaking effects introduced in Rise of Shadow expansion.
