I played a lot of zoo in wild when standard first hit and had a lot of success with it (finished rank 8 legend).  Two of the key neutral cards knife juggler and sea giant.  Aggro druid is a lot like zoo so I thought about trying those cards in the deck.  I think sea giant is better than bitter tide hydra overall.  If you play well and plan your turns sea giant usually costs no more than 5 mana (often times less) and with the popularity of shaman now bitter tide Hydra is almost a dead card.  Knife juggler has great synergy with your 6 (effectively 8) 1 drops and egg napper which in turn has great synergy with mark of y'shaarj as the death rattles are beasts.
