Since it costs 7, gifts from the past is not a 4 of, I would reduce it to 2 and put in some stuff to enhance your weapons since you are an enhancement shaman. Maybe mealstrom weapon, rockbiter, mend or end, or even windfury weapon.
Sentry totem isn't that great, except for a ferocity horde rush. I would put it into the sideboard and use something else like maybe magma totem or even some more enhancement to your weapons.
I would bring demonblood eviserator down to at least a 3 of, it is not something you want in your opening hand since it costs 5, maybe even a 2 of. Put in either some whispering blade of slayings or ashtongue blade. Ashtonuge blade is untargetable and all of a shamans enhancements for weapons do NOT target, they say attach to one of your meele weapons, not target, so they are perfect for a shaman.
The only turn 1 play you have is shamanistic dual wield (storm shock really isnt a turn 1, maybe 2 or 3 not 1), you really should add whispering blades so that you are guranteed a turn 1 play so you are not behind when you start. Not only that since you are daggering up, it would add to the damage of your other daggers, which is really needed to turn up the heat fast.
Sorry to be a broken record, but enhancement shamans are only good if they enhance thier weapons... It is their major win condition since they are able to keep up with a rogue for dpt (damage per turn, my new term) sometimes even able to beat them. Your major problems are going to be a weenie rush and balance druids with typhoon and cyclone and insects. Good luck and have fun!
mmmmmm.. that weapon is chock full of Shamany goodness... Finally!! a male enhancement......................... shaman!!!!
