These cards aren't necessarily bad, but this deck looks like Evolve Shaman and Control Shaman awkwardly smashed together. If your main focus is on Evolve potential, then Hallazeal, Elemental Destruction and Forked Lightning really aren't necessary, and you might want to have more double copies of minions than spells (except for Lightning Storm, Hex and Evolve, of course). And one copy of Nerubian Prophet would be good too. No underestimating the evolve value on that thing.

-Stormcrack, Lava Shock, Brann Bronzebeard

+Tunnel Trogg, Totem Golem, Eternal Sentinel

For better consistency and early game

-Arcane Giantx2

+Fire Elementalx2

Because Arcane Giant doesn't have anything to evolve into

Just a suggestion but it's probably how I'd run this.

What is Bran for in the deck there's only 5 cards it goes with.

This deck needs more early game. Your only 1-3 drops are feral spirit and totem golem, both of which have overload.

You're also playing brann with only 5 battlecries.  two of which that cost 6 mana.

In theory, it looks strong. Would'nt a bit more card draw help out a bit more.

Like  - Fire Elemental , +[card]Ancestral Knowledge [/card] and maybe some overload unlocks?

Awesome :) cant wait to give this a try when the expansion is out
