Hearthpwn

Its very simple to use as it runs some basic spells for drawing, controlling and making new spells, just over 1/3 of the deck is dragons so some of the combos are quite easy to pull off 

Bone Drake is helpful for obtaining even more dragons and finding some which are more suited for the situation, there are some dragons I think aren't good enough to run in the deck or they may be situational,(Sindragosa for example, I don't feel she is worth putting in the deck but can help with board dominance and drawing more Legendaries if you really need a boost in power).

Alexstrasza is nice to either save yourself temporarily or be more aggressive with your opponent 

Primordial Drake is really helpful to slow down aggressive decks which become too much to handle.

I'm quite passionate about this deck and would love any suggestions on how to improve it, sadly I'm not like other P2P players with ALL the Legendaries, but if I have the card I will try it otherwise I will have to ask you to try this deck out yourself with alterations and comment with some feedback, all will be appreciated :D
