The problem with Nerubian Egg is that you need to kill it somehow, as it has no taunt and no attack value. So I don't see how it improves early game when you need to combo it somehow to get it working. You'd need to either draw Abusive Sergeant or wait until you can get the Soulpriest out and make use of that. Or SCIENCE I suppose but I like to save that one for working around the Priest removal blind spot of 4 attack.
Shadow Madness to steal eggs would still require a way to kill the egg while it's in your possession. You would have to give it attack power this time, taunt wouldn't do.
I can see egg finding its way into Control Priest decks as they are now, considering they tend to run Sunfury Protectors and Defenders of Argus. Taunt that thing up and hopefully the opponent decides to smash. But mostly I'm seeing Silence becoming increasingly popular depending on which of these new cards see play. Which is why, though I kind of want to, I don't criticize the choice to include Mass Dispel.
I just don't know that egg is going to be as popular as people think. Surely the average player will be smart enough not to break it without silencing it, as it poses no immediate threat. I don't see it as being any faster or better than Ancient Watcher, perhaps more aggro as it can attack but it also runs the risk of being silenced and becoming useless. Whereas Watcher becomes MORE useful when silenced. Good for Shamans and Warlocks, don't think it will have mass appeal. But I could be wrong.
Edit: As long as we're calling New Meta I foresee a Deathrattle Deck, probably Shaman or Paladin for the extra mileage out of Deathrattles, with copious Rivendare action. I suppose I would lean Shaman since they do have cards that can either give a minion taunt or revive a minion when it is killed. Cairne becomes Quadruple Yeti, or perhaps even Sextuple Yeti!
(Play Cairne = 1 Yeti, Cairne Dies for Baine that's 2 Yeti, Proc Rivendare for another Baine for 3 Yeti, Revives from Ancestral Spirit for 4 Yeti, Dies Again for Baine again for 5 Yeti, Procs Rivendare again for whopping total of 6 Yeti.) So value, Much OP.
