This is an OTK deck with a very simple concept involving our beloved Shudderwock. The idea is simple: Shudderwock enters the battlefield with stealth from Coppertail Imposter and extremely high health, and the next turn we swap its attack and health with Crazed Alchemist and kill our opponent. For ensuring we deal enough damage with Shudderwock, we have two ways of granting it windfury: stable - Windfury, and unstable - Siamat. If Siamat's battlecry manages to give Shudderwock windfury, instead of casting Windfury itself we are able to drop Whirlwind Tempest and quad-attack with Shudderwock for immense damage.

How do we buff Shudderwock's health? Here our newest friend comes in - Faceless Lurker. Two of these guys with two Twilight Drakes buff Shudderwock's health to a minimum of 24 to a maximum of 96, which is an obvious overkill, but who cares!

The rest of the deck is control, healing and draw tools, as it is usual for any combo deck.
