Hello there :)

So much fun to try use Elwynn Boar and duplicate it many times to get Sword of a Thousand Truths.

1 step - draw a Elwynn Boar. First chance is mulligan, but you can get it with Tracking, Selective Breeder, Warsong Wrangler, Scavenger's Ingenuity or if it neccesary Maxima Blastenheimer.

2 step - duplicate Elwynn Boar again and again. You can use Pack Tactics to generate another one on board. But more relevant is to full your deck with extra copies of Elwynn Boar with well known Dire Frenzy or newest Devouring Swarm  to get boars back to hand or Northshire Farmer to shuffle them to deck.

3 step - when your deck or hand is full of 3/3 boars you can use Beastmaster Leoroxx to easily play from hand or Guardian Animals to play from deck. I would highly recommend use Beastmaster Leoroxx with Devouring Swarm if opponent have huge minion on board.

If boars and Sword are not enough to win game, you have another options. As hunter, always could use Hero Power :) With Aimed Shot to deal extra damage. Some secrets add to slow opponent. And Nagrand Slam to deal extra 12 damage (empty enemy board comes wiht 12 damage to opponent).

Have a good time and much fun with this deck!

EDIT:

I change one Nagrand Slam to Jewel of N'Zoth to get more Boars, cause they have deathrattle :) And more Elwynn Boar means more Swords in late game :)
