Hearthpwn

Typical silence priest only with Insight, Showstopper, Optimistic Ogre, and G'huun the Blood God from the newest expansion.

Insight allows you to bank mana for later turns when you don't want to overcommit to a board as your minions intrinsically have no effects or stickiness.

 Showstopper can activate lots of minions at once while being a road bump to your opponent. While they often get to decide when to pop it showstopper can force suboptimal plays and comes with a 3/2 body for 2 mana. It's also a huge bonus against token druid's early boards.

Optimistic Ogre is a meme the best card in this deck. It can bypass taunt for lethal, doesn't need silenced 50% of the time, has great stats for the cost and his great summoning line will keep you optimistic, an important trait to have in hearthstone. Truly a great friend.

G'huun the Blood God allows you to bank mana without overcommitting or create large tempo swings to end the game. This deck often has a high-ish health total thanks to how efficiently it can trade in the early to mid game.

This expansion gave silence priest a few new toys that boosts it's consistency and power in non-obvious ways, give it a try. Or don't.
