This is a Shaman Control/Combo type deck focusing around some silly things Shaman can do with deathrattle. It's a bit of a theorycraft, and I can't say I win with it very often, but it makes some pretty bananas things happen all the time, so you'll definitely have fun with it if you give it a few games. This deck would be much better if Shaman had good card draw -- you could pull off your insane control antics much more consistently. As is, the only card draw is Mana Tide Totem, and, in case you were wondering, yes, that's incredibly lame.
The real money makers are Ancestral Spirit and Reincarnate, when comboed with Kel'Thuzad and Stalagg / Feugen. Yes, Stalagg and Feugen are inconsistent, especially with bad card draw, but it is so very satisfying to have three Thaddiusses behind two Kel'Thuzads, especially when you have an Argus and Healing Wave in your hand, and 7 mana to spare.
You have 5-6 Nerubian Egg activators, in Rockbiter Weapon, Defender of Argus and Flametongue Totem. Between your hero power and deathrattle/sticky minions, you will have plenty of tokens to make full use of those activators.
Mana Tide Totem is the only draw I've included, so you have to make it count. It's best behind a taunt. It's also good to have some way to get rid of it, because if you leave it up for ten turns, it will start to mill you. Generally, if you get one draw out of it, and then your opponent uses a Frostbolt or Darkbomb to get rid of it, I'd call that a win -- you cycled a card, and took away one of their good cards, in exchange for one extra mana. That's good. It's not good when it gets attacked by a minion, but at least it gives you a little bit of stall and you still get the cycle. You can switch it out for Ancestral Knowledge if you want... Neither is a good tempo drop, but AK is the much better topdeck. I really hope Shaman gets good draw soon.
