I don't think there is a single cthun card that is broken tbh.
Not broken, but the 2/1 3-drop and 6/5 heal 10 priest minion are both really good.
What so broken about C'thun Deck? they completely beatable, and without Twin Emp as good as it is deck not gonna took off, Twin Emp himself not really took it to MC level IMO, the deck as it is tier 2-3 that viable for average player
I think its really fair for game to have really cheap and fancy deck like C'thun Deck but not really annoying like aggro deck.
Really not seeing this Twin Emp frenzy, your big minion usually just trade with both of them.. and the only burn in C'thun Deck is C'thun itself made it manageable threat.
Entombing Twin Emp with your own C'Thun deck feels good and gives you a 14-point buffer against their C'thun.
Control Priest is finally starting to feel a little bit better. It really, really depends on ASP though, and not drawing one hurts like hell. I've started including a single copy of Embrace the Shadow for pinches where I don't have one.
Alchemist is really growing on me, both in Control and C'thun. Most of the minions I'm running now have a lot of health, and being able to target the heal (or harm with ASP) is really strong.
Otherwise, I've lost twice to Anub today (pulled from Journey Below.) No matter how much Rogue changes, they'll still murder Priests. lol
