Menagerie decks surprisingly got some pretty good support from Rise of Shadows with the addition of Hench-Clan Hogsteed and Hench-Clan Hag.

Hench-Clan Hag in particular especially helps Menagerie Shaman since it has a battlecry that summons Amalgams which can now make Shudderwock a very powerful comeback tool and/or finisher for the deck.  From an empty board, just playing Shudderwock can give you a board of up to 4 Amalgams buffed anywhere from 1/1s to 7/7s with two random adaptations depending on the order of battlecries and how many Hench-Clan Hags, Zoobots, Menagerie Magicians and Gentle Megasaurs you've played, deny the opponent's board clear with Loatheb's battlecry and refill your hand with a Beast, Dragon, Murloc, and Lackey from The Curator's and Sludge Slurper's battlecries!  If you have a Dragon in hand, Shudderwock will protect the buffed Amalgams and your face even further by gaining Taunt and +1 Attack from Twilight Guardian's battlecry!

Playing to Shaman's strengths, I've taken a more Murloc heavy approach with this Menagerie deck to take advantage of Everyfin is Awesome. Soul of the Murloc can leave you with a board after a clear or trades and helps reduce the cost of Everyfin is Awesome in some cases.  Murloc Warleader and Gentle Megasaur are also both great ways to turn all the Murloc and Amalgam tokens into threats and the latter even fills a Beast slot for Menagerie buffs and The Curator draws!  Sir Finley Mrrgglton is another great Murloc for the deck that replaces the pretty useless Shaman Hero Power with something much more helpful and has great stats for sticking on board to get buffed by Zoobot on curve.  Life Tap or Steady Shot are the two best Hero Powers to get off him.
