The main win condition of this combo deck is to get an Emperor Thaurissan discount on Tundra Rhino, Gahz'rilla, and as many On the Hunt and Arcane Shot as possible.  Then, with 10 mana, Tundra Rhino and Gahz'rilla can be played on the same turn with the 1-mana spells, buffing the Gahz'rilla with Charge to do 24/48/96 damage in a turn, depending on how many 1-mana spells were discounted.  Even more damage can be done if a Wild Pyromancer is left on the board.  The Tundra Rhino and the On the Hunt hounds also have charge, which is useful if Gahz'rilla only has 24 attack, or to combine with a discounted Hunter's Mark to go through taunts.

This is not a particularly reliable deck, as is the case with any Hunter decks that require you to draw the vast majority of your deck.  There definitely are better OTK combo decks, especially in Wild.  Still, it succeeds often enough, and pulling off the combo is immensely satisfying.  I have slightly over a 50% win rate out of 65 games with this deck right now, mostly in Casual and low ranks.
