Quick idea for a malygos rogue with Emperor Thaurissan returning to standard. Also includes quest as getting other class cards seems an interesting package (Swashburglar should be better than Pilfer, Underbelly Fence is great to stop aggression, Vendetta can be used effectively and cycled with Gadgetzan Auctioneer). Finishing quest quickly would not be a priority, but finishing it would help you to survive till it's combo time. Maybe interesting to make space for Shaku, the Collector, although, depending on the meta, second Fan of Knives may be more valuable.

Except for Underbelly Fence, all minions are good/acceptable targets for Jepetto Joybuzz, although the card may be too slow.

Conceal would be used with Gadgetzan Auctioneer, but I am not sure if it's worth the card slot. Again, this is deck is an early idea.

No clue if it's going to work in the meta (the meta is going to dramatically shift). Alternative would be to drop the quest and some class stealing cards and include cards like Deadly Poison instead to fend off early aggression/cycle.
