Hearthpwn

Decided to try Hunter on my f2p id and I've used this deck to make a strong and fast climb to rank 11 over several games with a decent win rate.  It's basically a normal mid range hunter which uses azure drakes to tie the deck together.

You basically need to play on curve and dominate from the mid game on with draws from azure drakes and gaining board control.

This deck suffers a lot against Pirate warrior and aggro shaman, both of which are unfortunately the most prevalent decks on ladder.  But maybe after the upcoming nerfs, we see a decline in pirates?

Apart from these you have the potential to beat every other deck, especially the Reno ones, with enough firepower to kill them two times over with a lot of burst.

Against mid jade shaman, the easiest route to victory is to time your Timber Wolf + Unleash the Hounds combo  to finish for a lot of burst as they can't help but create huge boards with totems and golems.

Against miracle rogue it's simply a matter of who snowballs faster as rogue usually has a disadvantage with being able to clear with hero power.

Against jade druid, unless the druid draws perfectly, you should win most of the time.

Replacements:

Ragnaros the Firelord - yes, it can be replaced with another Call of the Wild or Sylvanas Windrunner or anything else that helps you finish really.

Snake Trap - You can replace it with Freezing/Explosive/Bear, but the tokens kinda help with Hunter's Mark / Timber Wolf / Leokk

Cat Trick - Can again be replaced with another trap/Eaglehorn Bow, but it's a really powerful card under the right circumstances

The Curator - Honestly, really  hard to replace because it draws you another Azure drake + beast in the late game and  provides a decent taunt. But if you have to replace it, then you could potentially fit in a tracking, but your win rate will plummet.

Flare- Normally used to ruin a mage's day or make rogues go wtf or as a cycle card in the late game (you really don't want this in your hand in the first several turns). Again, potentially replaced with Tracking

If you don't have Quick Shot or Kindly Grandmother, idk how to replace them.

 Give it a try if you have the cards or can replace them, but honestly you're better off spending dust on another class in a meta dominated by aggro on ladder.
