Murmuring Elemental is Mvp. IMO it is better than Brann Bronzebeard because it is 2 mana cheaper so you are able to combo way easier with the Jade battlecry's same turn. Brann never stuck around more than one turn usually anyway, and this allows for two copies!
Lots of ways to get jade cards back into your hand to make them bigger with Rummaging Kobold bringing back more jade claws that you can pair with Murmuring Elemental, and also Grumble, Worldshaker bringing back your jade cards.
Harrison Jones for all the new weapon legendary's that will be everywhere in the beginning.
Can't wait to play!
