This is mainly a Cruel Dinomancer deck, but I tweaked it to play more like Zoo at the beginning because I realised that when going for the Cruel Dinomancer interaction with Expired Merchant you tend to be placing all your eggs into one basket. 

With this adjustment the deck can contest early game with cheap minions and Eggs, shift into powerful lackeys in the mid-game withdark pharaoh tekhan, and finally seal the board in the late-game with Cruel Dinomancer.

For those unfamiliar the ulimmate combo in this deck is as follows:

1. Have Expired Merchant & Cruel Dinomancer in your hand.
2. Play Expired Merchant, effectively discarding your Cruel Dinomancer, you need to make sure that your Expired Merchant Deathrattle will trigger.
3. Play a Cruel Dinomancer on board, since it is your only discarded card in this game it will keep resurrecting itself in an endless loop.
4. Play Spiritsinger Umbra and then trade a Cruel Dinomancer to create a full board.

• Plague of flames is insaley strong in this deck as your board state is usually either cheap Lackeys, Eggs or Cruel Dinomancer, making other Zoo match-ups mostly in your favour.
• The deck is really hard to deal with for Control Warrior. I even had a good streak against RenoLock & RenoMage.
• Shaman is your worst match-up with so many transformation effects, but if you can bait the Plague of Murlocs & Devolve on your Eggs then you have a chance. 
• Priest's Psychic Scream & Mass Dispel can be annoying as well.
