What about that 8/8 for 6 mana guy that freezes himself after attack?

A pretty nice setup, kinda makes me wish I had some Faceless Shamblers to take effect of those high-stated minions. Though, aren't you worried about the deck's lack of outright removal? Sure the majority Silencing effects can be used to cripple some enemy minions if need be, but But having no copies of Death or Pain just seems wrong.

I agree with you on Crystalline Oracle, it is out of place in a silence deck. Tar Creeper will be important. If you drop a minion that can't attack/is detrimental to you, then your opponent will usually ignore it and go face. You need a cheap early taunt to protect yourself otherwise you will lose too much health and be unable to recover as there's not much healing. Your taunts are what will keep you alive in the early game. Dropping the Tar Creepers for another Sunfury Protector could work.

Emerald Hive Queen is a bit iffy. Ideally, you want to drop Ancient Watcher on turn 2, and silence it on turn 3. Emerald Hive Queen will have the best turn 1 stats of any minion in standard, so there's a chance it won't die, and you really don't want to waste a silence on it. I will test it out in my silence deck and see how it goes. I think Mistress of Mixtures will be better, as it helps to regain some of the early face damage and it trades well.

Divine Spirit and Inner Fire don't do much for you, it'll be a win-more combo. You should already be well ahead by turn 6 when your Bittertide Hydra is attacking.

If you were to drop 3 cards to replace with Deathwing, Divine Spirit, and Circle of Healing, which would you pick?
