I don't think card draw is a problem in your deck. I have been using a deck in which the only draws are from two Azure Drakes, two Mana Tide Totems, and Bloodmage Thalnos. From what I have seen, you have gotten zero value from the Gadgetzan Auctioneer (I think he is too gimmicky to use in Shaman).
Here are suggested changes to your current decklist:
drop Ysera, both Harvest Golems, Auctioneer, Cairne
add two Wild Pyromancers, an Argent Commander (or Leeroy), two Flametongue Totems
Ysera is great, but she is way late game. I've yet to see you have any use from her. She seems like a dead card. The same goes for Cairne - he is excellent, but he sits around in your hand, what good is he?
These additions would give you burst damage. Clearly, the Argent Commander (or Leeroy) would give some burst damage. I sorta like the Argent better because of the divine shield, so it lives and extra turn.
The Wild Pyromancers would enhance your board clear options against Zoo-style decks and cheap aggro.
And the Flametongue Totems would give you a bit of extra burst damage too. Use them to activate totems to for cheap trades, weaken larger minions to finish off with spells, or just the opponent's face. FTT are great little creatures.
I've learned from watching highrank streamers that immediate effects over deathrattles seem better, since deathrattles can be silenced away.
My two cents...
