Okay here's my shot at a Shaman Deathrattler deck:
2 x Earthshock
1 x Lightning Bolt
2 x Rockbiter
2 x Undertaker
1 x Ancestral Spirit
2 x Reincarnate
2 x Flametongue Totem
2 x Haunted Creeper
2 x Nerubian Egg
2 x Lightning Storm
2 x Harvest Golem
1 x Mana Tide Totem
1 x Baron Rivendare
1 x Bloodlust
2 x Sludge Belcher
1 x Argent Commander
1 x Cairne Bloodhoof
2 x Fire Elemental
1 x Kel'Thuzad
So far it's having good results, better than my Secrets deck anyways (for whatever that's worth). It's got a couple different viable win conditions.
1) Using deathrattlers, eggs and totems establish early board control. Get 4-6 small minions out before opponents have had a chance to draw into AoE and wipe them out with a well timed BLARGLEGARGLE (Bloodlust). (I wasn't sure this was viable when I started the deck, but I've pulled it off 3 times now and almost had lethal in a couple other games unbeknownst to my opponents.)
2) Have Mid-range threats (Rivendare/Sludge Belchers/Cairne/Fire Elementals) eat minion removal spells and then drop Kel'Thuzad to have a turn of trading while I've got a death rattler or two out building on that momentum to a win (this has been less relevant, but has been effective once or twice.)
This deck has lost when opponents have had heavy amounts of Silence in their deck or drawn board clear when I'm out of 1-3 drop minions in hand. For instance, once I got out late-gamed by a Priest who got both his Auchenai, CoH combos off, had a Rag I had to throw my Bloodlust at to remove, and had a Mass Dispel and a Silence to play. He also stole a copy of my K'T
which I killed with the Argent+something. I got him to start fatiguing, but couldn't draw enough to clear his board.
Anyhow thoughts? I'm not sure exactly what to do with Rivendare when I have him in hand, but he just seems like a good idea in this deck.
