Decided to post this list as it was my first time getting to legend in hearthstone. I used pretty much the basic dragon hunter list. It is a very good deck when piloted properly and can win games very quickly. I did make one change that seemed to help out the deck. I swapped 1x Imprisoned Felmaw for 1x Pack Tactics. This was a change made since a lot of people were playing around explosive trap so having this definitely messed with some opponents and lead to a win.
Our ideal keeps should be
Without Coin - 1 drop, 2 drop, 3 drop
With Coin - 1 drop , 1 or 2 drop , 2 drop , 3 drop
3 drop keeps - Primordial Explorer, Stormhammer
Don't keep Kill Command since this is more of a face spell to be used later so in most game we want to mulligan it and use more effective removal like Corrosive Breath (deals damage to board and face).
Coin gives us a lot of accelerated plays that can help us push more damage.
Some Examples are -
4 points of power on board on turn 1 is pretty hard for most decks to deal with.
One of my favorite turn ones. Sets up a very effective turn 3 for us.
Getting out Stormhammer and getting in damage or clearing any threats let us set up our cards for the coming turns. Primordial Explorer is best used with this example since it discovers another dragon.
Tips and Tricks
Corrosive Breath - You can target your own minion and it will still deal three damage to the enemy hero when you are holding a dragon.
Primordial Explorer - Some advice I will give is really take some time and think of what dragon you really need for state of the game. If its turn 6, your opponents at 10 life and you have the choice to grab Ysera or some more cost effective dragon. Take the cost effective one. Just because it is a strong dragon doesn't mean that we need it to win the game.
Thanks for viewing my decklist, I wish you best of the luck on the legend grind.
