If you want some fun and viability for the Double Deathrattler Battler Tavern Brawl then Reincarnate Shaman is your answer. The deck is great in this brawl because it can stack up a board and punish your opponent. I added Annoy-o-Tron because I felt like I really needed to get out of the early game, and getting an Ancestral Spirit on Annoy-o-Tron really takes the wind out of an aggro decks sails. Defender of Argus forces your opponent to trade into Deathrattle minions, and Lil' Exorcist will take advantage of their board. Sludge Belcher is very tough to deal with, and an Ancestral Spirit and Reincarnate on Sylvanas Windrunner will usually swing you the game!
