I appreciate the feedback. If you'd be willing to continue the dialogue so we can exchange ideas I'd truly appreciate it.
Only at level 7-8 assuming they haven't already taken damage and assuming there aren't any spell damage amps down prior.
In my current Priest play style, I try to constantly trade down minions in all match ups. I want his board cleared, and my guys healed. Flamestrike is a very costly move for a mage, and many only run 1 these days. There will be mages that get the better of you, but so far Yetis and other solid mid-range minion are a major backbone in my current deck.
Honestly, I'm not sure there's any other effective way of dealing with early aggression aka Merloc decks and the like. I think you're overlooking the silences in my deck too, which make them a bit more versatile. I can have a 4/5 with taunt out on the bottom of 2 or a 4/5 attacking precisely because there are so many of those cards. And they're cheap as hell all game, meaning I can lay them down at various points when I'm bleeding mana and they will often not be dealt with until I make them a threat. Plus, as a bonus, if the opposition tries silence them to get around the taunt, I get a 4/5 to attack with.
I still run a Pyromancer, and he's worth his weight in gold in these situations. Between him, the Holy Smites, the SW:P's, etc, I can usually hold out until turn 4, where I drop a Tazdingo. I haven't had any trouble with Murlocs in a while, and I'm starting to figure out Hunters, too. There are those times when I just get a bad opening draw, and the other guy gets everything he wants, but those are probably going to always be an issue for Priests in the current meta.
I get your idea on the Watchers, but economically, running so many of them and the protectors doesn't jive with me. For 4 mana / 2 cards, you get a 4/5 taunter, which is only slightly better than Sen'jin, and if you go the silence route, you're still looking at 4-6 mana and 2 cards for what's essentially a Yeti. I'm not saying to pull them from your deck, but I think you could get away with running one Watcher, Protector and Argus, each, and not be loading down your deck with minions that require combos.
I tired running him for a while... and while he can't be silenced, the immediacy of a 4/3 on often found him targeted over cheaper minions and then those dealt with later. Frankly, I found Circle of Healing and Blademaster to be far too situational... and never something I could rely on.
The Blademaster + Circle combo is definitely a nice-when-it-happens thing. I don't rely on it. I try not to play the Blademaster until I know I can heal him. If I drop him with the first 3 or 4 turns, it's because I'm desperate. Still, at only 3 mana, if you do have to trade him early, it's not like you're out some expensive card. My play style has been centering heavily on healing my guys. I've only reached level 15 with this deck, but I'm on a win streak (4 stars) so I may be able to take it further, tonight. We'll see...
I posted my current deck in a another thread. Please feel free to check it out and offer any feedback. :)http://us.battle.net/hearthstone/en/forum/topic/11747004611
