It seems fun but the problem is Spirit of the Shark is simply not a good card, and there's countless replay data to back that up, and you've built the main combo of your deck around that card.  This meta is strong in aggro, so unless that changes this is just a fun deck, not a good deck unfortunately.  Still props for actually deckbuilding, I'll give it a try if the meta shifts.

I was just going to update this deck by removing ×1 spirit and ×1 questing explorer and adding ×2 Pharaoh cat

I tried it and the win rate increased in ranked games, pharaoh cat is such a good card 

The reasons for spirit and questing is that during playing you don't need two of these cards, the quest sometimes is done quickly and the spirit without some cards is way too bad on it's own 

I tried this out without the quest and explorers (I don't have the quest) and it felt so clunky. The Firetree Witchdoctors rarely are active Without extra dragons and are just bad tempo or are dead in hand. I added an extra copy of Faerie Dragon and a crowd roaster to help but it didn't matter. Rogue just doesn't a big enough spell pool to justify King Phaoris. I liked the idea initially but after playing it, I decided it was too bad.

I think it's about the cards you mulligan

 Mulligan for: backstab and pharaoh cat (I've just added this), try to keep a dragon in hand if you had the coin and since you don't have the quest dont start with "add from another class" cards and try to start with low cost cards

But I don't think that without the quest this could work, the quest is good with this one, it can defend you and works good with other cards
