10 mana combo, can be done as early as T5 by setting up Shark on T4 and coining out the rest of the combo on T5:

(4) Spirit of the Shark + (2) Foxy Fraud + (0) Scabbs Cutterbutter + (3) Alexstrasza the Life-Binder + (0) Tenwu of the Red Smoke + (1) Alexstrasza the Life-Binder for 32 damage.

Alternatively, do the same thing but instead of Alexstrasza the Life-Binder, play Oil Rig Ambusher four times with Tenwu of the Red Smoke + 2 x Shadowstep to deal 28 damage for 9 mana, after which Sinister Strike can be used to get 31 damage in total. Doing the combo the turn that Oil Rig Ambusher is drawn does 32 damage instead for 9 mana.

Efficient Octo-bot can obviously be useful for getting the combo out eariler.

The name is inspired by Scabbs and Shark (and maybe Octo-bot), since Scabbs is a chef :D
