Greetings,

Here is the deck I used to defeat Kael(Thas Sunstrider. This match is quite difficult (quite normal, it's one of the last boss...). The WR is decent but you might need few attempts to succeed. In particular, if Kael'thas plays a lot of small spell early (especially Incanter's Flow or Ancient mystery it smells bad.

How is built this deck (and why it works)

This deck a variation of dragon hunter but with a lot of "evasive" cards.

• Dragon hunter is a strong archetype and here we only kept the best dragons knowing the boss decklist involves mostly spells. 
• Actually this is what block the boss, because many spells require target. The less he has target, the less his power effect triggers and the longer the match lasts, hence increasing your winrate. Suprisingly the Ai plays highly defensive when you have a board he cannot manage and this is why the deck works.
• Your win condition is typically Alexstrasza face and eventually burst to complete (Nagrand Slam, Kill command)

How to play this deck

• Fill the board with evasive minions.
• Cast spell to manage early opponent's minion (Starscryer, Al'ar, Astromancer Solarian, Pyros).

Possible replacements

• Alexstrasza is highly strongly advised.
• Dragonbane can probably replaced another Nagrand Slam or Toxic Reinforcements or by a good charge minion, 

Good luck and if {you enjoyed this deck / this deck helped], feel free to upvote it :-)
