So to start off that's an tempo deck which relies on maintaining board control through value trades and highly efficent spells.

I will try to explaing why i chose some cards one by one:

1. Blood To Ichor : Really efficent 1 mana spell which can activate your Execute and put a 2/2 body to the board and some times adds that 1 damage that you need to make a trade.

2. Execute : No need to say why i put that card,its so powerful and its a hard removal.

3. Battle Rage : Very good card helps you draw at least 2 cards, and refill your hand. Often you have more than 1 damaged minion due to value trades that you must make so this cards value is huge.

4. Bolster : Insane with Protect the King! and the reason we play this deck!!

5. Slam : Really good card activates your Execute too. Help you make trades and recycle  your hand.

6. Fierce Monkey : A good 3 drop with Taunt that helps you gain tempo and stop some damage from aggro decks. Works well with Bolster also.

7. Frothing Berserker : An enormous threat which must be cleared immediately by your opponent . If you can help it stick on the board for a few turns It can unleash a great power.

8. King's Defender : A card that has synergies with our taunts. Even if you dont have an early taunt like monkey you can play it at 3 mana and make some trades. Helps a lot versus aggro decks.

9. Protect the King! : Also the reason we play this deck. It makes wombo combos with Bolster and annoys every aggro deck out there.

10. Bloodhoof Brave : Awesome taunt, hard to clear. If you need that extra damage from enrage you can acivate it with Blood To Ichor and Ravaging Ghoul

11. Kor'kron Elite : Really agressive card. You can use it for face pressure or efficent trading. Trade with the 2 attack minions and stays at the board. Really good tempo card.

12. Obsidian Destroyer : In this deck that card can work pretty well, the dream is to come out with Varian Wrynn and dont forget that 1/1 that summons at the end of the turn its a taunt that annoys every aggro and non deck force them to overkill it most of the times.

13. Grommash Hellscream : Good game finisher with Blood To Ichor to deal 10 damage and you can also use it for efficent trades.

14. Varian Wrynn : Strong late game card, can pull out insane threats and some taunts to stop your opponents and sometimes end the game.

15. Sylvanas Windrunner : Strong 6drop hard to clear. She is always annoying and gives you great tempo even if you are behind on board.

16. Ragnaros the Firelord : Huge creature which should get traded immediately by your opponent . If he doesn't you will surely get a big advantage from it's value trades.
