Why name it "Innervate" then and not yet another Counterfeit Coin? It won't be seeing much play now. Decks other than the usual jade, plague, aggro that utilize the card become a lot less powerful...There goes my quest druid...I would rather have it changed to one of the other things that were taken to consideration like "Gain 2 Mana Crystals this turn only and increase the mana cost to 1".
I am ok with the Murloc Warleader change, though I don't play too many murlocs myself I am pretty sure that the card will still be just as usable as Knife Juggler still is. Definitely not uncalled for.
As for Fiery War Axe I am thoroughly disappointed because control warrior takes yet another hit. I couldn't care less about Pirates,I barely played the deck. First it was Execute and now this...If things weren't bad enough as it is with Scourgelord Garrosh having one of the worst Death Knight hero powers here comes a nerf that erases any chances for a good control Warrior deck to see play other than quest Warrior. I would rather see changes in other cards that every Pirate Warrior deck utilizes such as Arcanite Reaper, Kor'kron Elite or even Heroic Strike. The description clarifies that the change was made to lower the power level of Pirate Warrior(as Pirates complement Fiery War Axe's usage) but apparently they didn't consider what the effect is on other, less popular archetypes...
I never understood why Hex cost one less from the very similar removal spell from Mage, Polymorph. Maybe because Shaman used to have a less enticing card set in the past and one less mana cost(compared to Polymorph and giving the transformed minion taunt) was to complement his weaknesses compared to the rest of the classes. Again Control oriented Shaman decks take a hit while the most popular aggressive evolve shaman decks don't, as most of them don't even run the card. It might still see play but players will definitely think again about slotting a 2nd copy of it.
Spreading Plague is a card we all knew it was too good for it's mana cost. A shame it took this long for the change to take effect. Definitely a better way to represent the card's power level with an added(+1) mana cost.

Well, on some happy occasions you can do Preparation, WANTED!, two coins and 10/10 Edwin VanCleef on turn one, also killing what your opponent played on his turn. On other occasions it may be a bit trickier to play, but may be still viable.

Swapped Moorabi for The Lich King. No regrets so far.
