The idea is that you can find Halazzi, the Lynx using Tracking and Stitched Tracker. You can complete the quest using that new legendary only.

Before and after the quest is done, you play the deck as a normal spell-secret hunter.

Of course, you have to make at least 7 1mana drops from Halazzi, so your hand has to be fast (that's mostly why the curve is low) - you have to have max 4 cards in your hand when you play Halazzi (4-1+7=10).

EDIT: You can consider adding Zul'jin - that hero has to be tested. Rexxar hero power looks too good to be replaced tho..

EDIT2: Against aggros you can consider to mulligan the quest away - the deck looks overall solid (well, that's because spell hunter has a good matchup against aggro decks).

Not 100% sure about: 

• 1x Toxmonger and 1x Animal Companion - The first one is too situational, it can be replaced with the second Animal Companion or something else. Doing so, you also have 100% discover from Stitched Tracker.
• 2x Unleash the Hounds.
