Template:Shudderwock strategy
Shudderwock is a powerful value play that requires specific deckbuilding. In order to reach late game to have drawn and played Shudderwock, the deck needs a strong Control backbone. Shaman has access to several powerful control options, such as 
Volcano and 
Lightning Storm. Strong Battlecries to copy include Elise the Trailblazer, 
Hagatha the Witch, Kalimos, Primal Lord, Baleful Banker, and 
Zola the Gorgon. Shudderwock is fairly weak with targeted Battlecries like Hot Spring Guardian and Fire Elemental, since it leaves these effects up to chance.
Shudderwock can be used to close out games by repeating the Battlecries of Lifedrinker, 
Doppelgangster, 
Saronite Chain Gang, Grumble, Worldshaker, and Murmuring Elemental. Lifedrinker will deal high damage to the opponent when repeated enough, Doppelgangster will create more Shudderwocks, Grumble will return the Shudderwocks to your hand and reduce their cost to 1 allowing you to play another Shudderwock, and Murmuring Elemental will cause your next Shudderwock to activate twice. To improve the consistency of this combo, you can use Fire Plume Harbinger to reduce Murmuring Elemental's cost and Sandbinder to draw several combo pieces.
Like all combo decks, decks focusing on Shudderwock are vulnerable to Aggro and Tempo, which can defeat them before Shudderwock is properly set up.
