This deck is a hybrid of all the other Shaman decks currently running around. It actually works really well! there is a few combos that work together.

You have you thunderhead in there with a few overload spells to take control of the board and be a bit aggressive if need be, the spells  have good synergism with the Bloodmage.

Doomhammer and Rockbiter which is excellent in the current meta in my opinion. 

Electra and any combination of spell.

The Galkarond invoke cards are good for board control aswell.

Ideally you want to mulligan for any of the lacky card providers. Slurper, or any totems, Bloodmage or invocation of frost.

Give it a try and tell me what you think.

Cheers
